Uber spent more money campaigning to prevent a law requiring background checks on drivers in one city than it would have cost to do background checks for all their drivers in the entire country.
These companies can try to claim it's about making things better all they want. It's clearly just about money to them. I learnt that the hard way trying to deal with AirBnB.
Tip: companies "doing the right thing" don't charge your credit card then require you to login with Facebook (which I don't have) or upload a video explaining why I want to rent a house.
