No one cares... outside of tech circles. Even then, I bet a ton of people will still use it, why? Convenience, price and "what does that have to do with me?" mentality. If I am being honest, I will still use Uber... especially in Colombia and other places where it totally obliterates cabs.
Contact them directly and express concern over business practices or behavior.
Contact your government representatives and ask them to regulate Uber and their business practices.
Share news reports with your friends so they understand the problem as well.
I don't use Uber or Walmart because I feel these companies are destructive (on balance) to society. That doesn't prevent me from complaining when Lyft or Target fails to be a good corporate citizen.
