Communication models
"The imparting or interchange of thoughts, opinions or information by speech, writing or signs." — Macquarie Dictionary
| Model | Focus | Strength | Weakness |
|---|---|---|---|
| Transmission | Transfer of messages; mechanical (source, receiver, feedback, noise) | Useful for constructing clear messages | Human communication is not mechanical; oversimplifies meaning |
| Transaction | Creation and negotiation of meaning between two or more parties | Useful for complex conversations, negotiations; checks shared understanding | Less helpful for understanding how ideas spread in society |
Freedom of speech and censorship
WANT online DON'T WANT online Open access to information Spam and scams Freedom to communicate Terrorism content Uncensored knowledge access Paedophile content Network neutrality Cyberbullying and harassment
Australia's position (from ICT521 FAQ)
Free speech is not a constitutional right in Australia. There are dozens of laws limiting speech in the public interest — criminal law, contempt, broadcasting, intellectual property, and secrecy legislation. "Limitations are appropriate because freedom of speech doesn't mean the right to say whatever you want wherever you want." — Prof Katharine Gelber, University of Queensland.Internet governance challenges:
- No single entity owns the internet — amorphous and constantly growing
- Nodes reside in countries with different laws — jurisdictional coordination is difficult
- Network neutrality: all internet data treated equally regardless of content, user, or device — EU law, but not US law
- UN Working Group on Internet Governance requires buy-in from sovereign governments to implement controls
Ethical issues in online communications
Cyberbullying
"A form of bullying or harassment using electronic means." — Examples: posting rumours, threats, sexual remarks, victims' personal information, hate speech.
Why it is worse online: anonymity removes social consequences; reach is global; content is permanent; harassment can be continuous. IT professionals have a responsibility to design systems that minimise harassment, not treat it as an inevitable feature.
Anonymity online
| Positive (protect) | Negative (risk) |
|---|---|
| Freedom of expression without fear of reprisal | Enables cyberbullying and cyberstalking |
| Protects whistleblowers and political dissidents | Enables dishonesty and identity fraud |
| Allows marginalised communities to speak safely | Reduces accountability for harmful speech |
| Reduces fear of surveillance | Multiple/hidden identities amplify harm |
Email and spam
- 3.8 billion email accounts; 281+ billion emails/day
- ~80% of all email is spam
- 91% of all cybercrimes start with an email
- Opt-in: user must affirmatively consent to receiving emails (ethical default)
- Opt-out: user added by default and must actively unsubscribe (less ethical)
- Australia: Spam Act (2003) enforced by ACMA — penalties up to $2.1 million per breach per day
Social media ethics
- Privacy: companies collect and monetise personal data; users often unaware of extent of sharing
- Marketing: sponsored content and fake reviews without disclosure
- Cyberbullying and harassment: should not be accepted as inherent features of online environments
- Trust: can you trust consumer reviews, company-sponsored groups, or advertorials?
Questions
Discuss the ethical issues with online anonymity. Should anonymity be protected?8 marks▶
Online anonymity is one of the most contested ethical questions in ICT because the same feature that enables legitimate protected expression also enables serious harm. Both dimensions must be fully analysed.
The case for protecting anonymity:
- Anonymity is a fundamental component of freedom of expression — it reduces fear of reprisal and enables speech that would otherwise be suppressed
- In authoritarian contexts, anonymous internet access enables citizens to report government misconduct, organise political resistance, and access censored information safely
- Whistleblowers who expose corporate or governmental wrongdoing frequently depend on anonymity — their safety requires it
- Victims of domestic violence, political dissidents, and marginalised communities have genuine safety reasons to communicate without revealing their identity
- Removing anonymity would silence these voices disproportionately, imposing the greatest harm on those already most vulnerable
The case against unrestricted anonymity:
- Reduced accountability enables cyberbullying, cyberstalking, and hate speech at a scale and intensity that offline environments do not permit
- Research consistently finds people behave more aggressively and dishonestly when they believe they cannot be identified
- Online anonymity allows people to express hostility with no social consequences, making harassment more intense and more persistent than offline equivalents
- Online scams, phishing attacks, and misinformation campaigns all depend on anonymity or identity deception
- The ability to maintain multiple or hidden identities amplifies all these harms
The ethical framework for IT professionals:
- Anonymity should be protected as a default — this satisfies deontological ethics (freedom of expression as a universal right) and respects individual autonomy
- Proportionate, due-process-governed limitations should be available when anonymity causes concrete, verified harm — this satisfies utilitarian ethics (maximising overall welfare)
- In practice: design systems with anonymity by default, identity verification mechanisms available for legal processes, clear community standards, and moderation workflows that do not require revealing identity for ordinary platform use
- The goal is not to choose between anonymity and accountability as absolutes, but to build systems that preserve the legitimate functions of anonymity while creating sufficient deterrence against harmful anonymous behaviour
What is Australia's position on freedom of speech online? What are the implications for IT professionals?6 marks▶
Freedom of speech is not constitutionally protected in Australia, unlike in the United States. While Australia recognises freedom of expression, its laws are primarily concerned with defining its limitations rather than guaranteeing its existence. This distinction is practically significant for ICT professionals operating in the Australian context.
Key aspects of Australia's position:
- There are dozens of laws across the country limiting speech in the public interest — criminal law, contempt of court, broadcasting regulations, intellectual property law, and secrecy legislation
- No single constitutional protection for free speech means each law must be assessed on its own terms
- Professor Katharine Gelber (University of Queensland) notes that limitations are appropriate because freedom of speech does not confer the right to say whatever one wants wherever one wants
- Defamation law is particularly active in Australia — ordinary social media users have found themselves defendants in defamation proceedings for posts they considered ephemeral or trivial
- Australia has specific laws on cyberbullying, online harassment, and the sharing of intimate images without consent
Implications for IT professionals:
- Platform operators must comply with content moderation obligations and may face legal liability for hosting illegal content even if they did not create it
- IT professionals designing communication platforms must build in mechanisms to identify and remove unlawful content while preserving legitimate expression
- The American tech company culture of "free speech absolutism" does not apply in the Australian legal context — professionals working in Australian-facing products must understand this difference
- Beyond legal compliance, IT professionals have an ethical obligation to exercise judgment about how systems are designed and governed, treating legal minimums as a floor rather than a ceiling
- The professional-society relationship (Topic 2) requires actively working to improve quality of life, which includes actively preventing harm through system design, not merely avoiding legal liability
Spam represents 80% of email traffic and 91% of cybercrimes start with email. Discuss the ethical and legal issues.6 marks▶
Email is the most widely used professional communication tool globally, and its near-universal adoption makes it both the primary channel for legitimate communication and the primary vector for cybercrime and unsolicited commercial communication.
The ethical issues with spam:
- Spam violates the principle of informed consent — recipients have not agreed to receive these messages, constituting an invasion of their time and digital space
- The opt-out default (add users by default, let them unsubscribe) exploits user inertia and is ethically inferior to opt-in (require active consent before sending)
- Spam is frequently used as the delivery mechanism for phishing attacks, malware, and financial fraud — organisations that send spam create the infrastructure that criminals exploit
- At 91% of cybercrimes starting with email, the design decisions made by email platform providers and the compliance choices made by organisations directly affect the incidence of crime at a societal level
The legal framework in Australia:
- Spam Act (2003): commercial electronic messages must contain sender identification, a functioning unsubscribe mechanism, and must be sent only to those who have consented
- Enforced by ACMA (Australian Communications and Media Authority)
- Penalty: up to $2.1 million per breach per day — one of the highest spam penalties in the world
Implications for IT professionals:
- Design marketing systems and CRM platforms with opt-in as the default, not opt-out
- Implement functional unsubscribe mechanisms that process requests within required timeframes
- Apply email filtering and anti-phishing measures to protect users from criminal exploitation of email infrastructure
- Treat the legal minimum (Spam Act compliance) as the floor, not the ceiling — the ethical standard is opt-in by default, transparent identification, and immediate unsubscribe
