I'm pretty sure there are a lot of people upset with them. I use uber pretty regularly, and there is no way in hell I agree with the government sponsored monopoly that taxis enjoy, but I don't like them. They're a shady company with shady legal practices.
In Seattle, there are probably 50 uberx drivers for every lyft driver. I don't know why they haven't caught on more, but they aren't much of an option.
