Interesting that OpenAI is trying to hammer the point that they won't sell user data to advertisers.

That's how all the major ads platforms work. I don't personally agree that it constitutes "selling your data" but certainly people describe it that way for Google/Meta ads which function the same way. By framing it this way they're clearly trying to fool users who really bought into the messaging that Google et al literally sell user data when they only provide targeting. I guess the hope is that the cleaner reputation of OpenAI will mean people think there's some actual difference here.
