I agree that HR should not behave in the ways it's claimed they did. However, based on my perception of Uber's willingness to ignore rules, I find it believable that they could have an HR department that thinks such actions are a good choice; I also wouldn't be surprised if they don't do any of the state mandated harassment training either for all employees or the addition training for managers.
I also believe the claims because they are very specific, egregious, and should be verifiable; and they were related in a simply facts manner: there were no questions of intent or what the other people were thinking, and only a limited amount of heresay. Additionally, it felt more like a "this kind of thing is happening, you should watch out for it" than a call for pitchforks and torches.
Willingness to ignore rules does not lead to these actions. It's nonsensical. There is no way you would tell a complainant that you were protecting a manager because they were high performing. You would be extremely secretive about that. There is no way you would tell a complainant that they should expect a negative review for reporting sexual harassment. You would placate them to make the problem go away.
