I disagree that they have zero brand loyalty. Yes it is a price sensitive industry but you're doing something right when your brand becomes a verb. I'm in Melbourne, Australia and I generally pay the extra few dollars for Uber rather than dealing with Didi, Taxify et al's inferior interfaces and slower pick up times. I think Uber take 28% commission vs Didi's 15% and that is reflected in the pricing eg. a $25 Didi fare is usually $30ish on Uber.
