I'm in full agreement. So many cases of this, and many other others such as falling out with management and peers, new more lucrative offer, and so fourth. Its obvious that these people who come forward are not going to suffer for their new found moral compass.
Or just very dubious timings. Like the other guy from Anthropic that was all over the international news. No followers, no post history but a single post blows up "naturally".
Highly suspect trends that can only make one believe it's marketing.
