To be fair, in this one Meta is intentionally publishing these on their front page, while OpenAI is subject to a legally mandated retention policy pursuant to an ongoing lawsuit. While I think both are problematic, the Meta one seems much more underhanded.
I don't understand the outrage about the court order and chatgpt. Is user data retained by a tech co somehow exempt from discovery? Say you're suing a company over mishandling user data, wouldn't that data become material to the case?
