I don't think that what Aaron did was* wrong.
Meta's wholescale theft, however, is pretty hard to defend, and Meta knew it. That's why they went to some lengths to hide it.
Similarly, that OpenAI whistleblower, the one whose family was calling for a murder investigation, might be alive today if it wasn't pretty well known that stealing the work of thousands/millions of people to make a for-profit imitation machine isn't exactly cool or legal.
Edit: egregious typo.
