I don't buy that chatGPT is actually doing these users any harm. I think openAI is doing the best they reasonably can with a very difficult class of users, whose problems are neither their fault nor within their power to fix.
If anything, my use of AI (admittedly not as a companion or a psychologist) suggests that it is on the whole significantly less toxic than the seething cess pit of social media. AI is positively affirming by comparison.
LLMs are far less toxic by comparison, but people are all about censorship in this case because they don't like the vibes. If lawyers and activists force the frontier labs to completely lock down their models, people will just go to open weights models that have no protections at all. This is already happening to some extent.
It's also interesting that people are always going after GPT when Claude's guardrails are far less strict. 4o caused OpenAI to overcorrect in my opinion. Again goes to the point that these arguments are more founded in vibes than reality.
