I don't feel Lyft is some paragon of virtue. AFAICT they're a regular Silicon Valley tech company with all of the usual tensions associated with that. The service they provide is a huge improvement on what came before, but there are privacy concerns related to the data they collect and use for business purposes. They'll probably push the envelope a bit on what they can do with that information, and then back down whenever there's significant pushback.

Uber, on the other hand, is a cesspool. It's run by sociopaths who think business success confers moral authority, and are quite annoyed with all the hullaballoo about "right" and "wrong" that their actions periodically provoke.

I have no problem with their business model, but I will not use Uber. I don't trust them with my credit card, and I don't want them tracking my movements.
