I'd also point out that swaths of people probably already have left Uber and tons of other companies for unethical practices.

You just don't notice because they get replaced, and the new people assume that existing practices are the norm. The world keeps spinning.

I guess my point is, if you don't see many people leaving at once, that isn't evidence there isn't something fishy going on. People have families, mortgages, children's tuition payments...
