Going to hazard a guess that OpenAI is using LLMs to read convos and decide which ads you should see? Hopefully that's isolated and locked down. I can easily see that machinery turning from "what ad should we show this user" to "is this user doing something bad/a protected class etc.". Also terrifying to think that it may be the advertisers asking the questions to decide what ads to show...
