What is a key ethical concern with social media data collection and advertising?

• A. User privacy is often sacrificed for security and profit.
• B. All data is always fully anonymized.
• C. There is no ethical concern.
• D. Data collection guarantees user safety.

Answer: (C)

The central issue here is privacy and consent in the face of business incentives to harvest data for targeted advertising. Social media platforms collect vast amounts of personal information—what you post, what you click, where you go, who you interact with—and then combine that with data from other sources. This enables highly precise profiling and targeting, which raises ethical concerns about how much of your private life is accessible and how transparently you’ve agreed to it. Even if a platform claims data is anonymized, real-world experience shows that people can often be re-identified by linking datasets, so assurances of full anonymity are misleading. Data collection also does not guarantee user safety; more data can reveal preferences and vulnerabilities that could be misused or misrepresented, and it can expose users to manipulation or discrimination.

So, the best framing is that user privacy is frequently sacrificed for security and profit. The idea that there are no ethical concerns, that all data is always anonymized, or that data collection guarantees safety does not hold up to these considerations.
