If it was "very clear", OpenAI wouldn't be threatening the researcher with "it's very bad for your career" or state "we can't tell you if it was trained on user input".

Additionally, according to the researcher, OpenAI's proof follows the same approach they used, and which was largely unused in academia, but OpenAI claimes they arrived at it immediately.

Bullshit.

Ain’t no way you read one 100 page paper let alone two with enough understanding to make such a claim.

You ought to be ashamed of yourself.
