The only things that matters to the average user is the experience and the price - in order for people to stop using Uber something has to affect them personally.
I've never personally had a bad experience with Uber or Lyft, and unless that happens, I'll continue to use their services. The bottom line is I just don't care THAT much, i'm more concerned with my life.
That's signaling. It's a mating strategy. Whether that actually changes the behavior of all those who are signaling when they aren't being observed by others in their in-group is another matter entirely.
