Also worth pointing out that it is not an ad hominen.

Ad hominen is when you attack someone who is making an argument, instead of an argument. "You are flawed, which means your argument is flawed", but that does not follow. If you were in a debate with Epstein or Musk, and he said "2 + 2 = 4", there is no fault of their character that could make the statement untrue.

But nobody is making that argument. "The leadership" being criticized is not even a participant in this thread (presumably). "The leadership is flawed in this manner" is a statement that can be true or untrue, and "So their product and followers are flawed in these other manners" is something which can follow.
