It isn’t, but the GDPR requires companies to scrub PII when requested by the individual. OpenAI obviously can’t do that so in theory they would be liable for essentially unlimited fines unless they deleted the offending models.
In practice it remains to be seen how courts would interpret this though, and I expect unless the problem is really egregious there will be some kind of exception. Nobody wants to be the one to say these models are illegal.
I do this a lot (not in public) because it’s way too easy to hang up with your ear and it fatigues my arm after like half an hour. It’s fine as long as you don’t shout into the phone.
