>was one individual who made those bad choices over and over

This was never said, or even implied, in the article. We don't even know if this was a single person choice.

You are making up "facts" like calling the person who makes mistakes "toxic", or saying that the choice was made by someone who only made bad choices.

We are talking Uber here, in 2017, which was not only playing "move fast and break things" but "move really fast while shooting an AK47 blindfolded". Not only they expected mistakes, but they encouraged them. It would be plain wrong to start firing individual people for making mistakes if that is the environment.
