I question the ethics of anyone choosing to work at Uber, period. It’s been blatantly obvious for at least two to three years that they are corrupt, not just “disruptive”. And that’s just based on the news we get in public; there were probably internal signs long earlier.
I speak as someone who once worked at a corrupt and unethical company (in Hollywood) and who got TF out of there within months, as soon as it became obvious internally.
