It’s debatable that it was debunked. There was squirrelly wording about some specific claims. One person was reported to have been offered a package worth a billion dollars, which even if exaggerated was probably not exaggerated by 10x. The numbers line up when you consider that AI startup founders and early employees stand to potentially make well into 9 figures if not higher, and Meta is trying to cut them off at the pass. Obviously these kinds of offers, whatever they really look like, include significant conditions and performance requirements.
