It's a losing battle in that the CC license and StackOverflow's ToS make it clear that StackOverflow is allowed to restore the post regardless of the original author's wishes. It's less clear that the license gives AI companies the right to train LLMs. They tend to take the view that any media can be used for training regardless of licensing because it's fair use. Many authors disagree and believe they must explicitly license their content for LLM training. AFAIK none of these legal disputes have been settled yet. In my view you shouldn't really expect to have much control over who uses the content you post to Stack Overflow. Maybe your answer will be used by a CS101 student. But it could also be used by a defense contractor, gambling site, North Korean hacker, or darknet drug marketplace. Yes, the license requires attribution, but if ChatGPT ignores that requirement it's behaving like 90% of programmers.
