Many large tech companies condemn or criticize the troll's partial Muslim ban, but Uber took the opportunity to undercut the taxi drivers' protest strike.

Now many users are boycotting Uber demanding that it stop helping the loser. This would be a good reason to boycott Guber, and it adds to the other reasons, such as mistreatment of its workers.

But even without a boycott, customers should reject Guber (and other such services including Lyft and Bridj) because they are surveillance systems and require running a nonfree app.
