Maybe Twitter works yet because remaining staff is overworked, which kind of defies the point. Making drivers life easier by making engineers burnout is maybe a net sum, but does not look ethical

Also, taxi drivers in many countries are notorious for their dubious behavior. At first, ride-sharing was not like that. Now, it looks like a downfall.

Other then that, ridesharing provides valuable services. Many people hate calling. Security and reliability is higher in ridesharing. Convinience, too. Imagine calling for a taxi in foreign country vs calling an Uber.
