My city's taxi system was completely changed by Uber, as were many parts of the country. So while it might not be true anymore, and taxi drivers with bad attitudes and those fudging the meter might have been mostly weeded out, it's because of Uber that this happened. And it's because of their unions that it hadn't happened before. But the moment there started being some competition in town as opposed to their previous monopoly on the market, they had to back down if they wanted to even survive, let alone come out on top over Uber.
So while yes, uber employees are being fucked over, that has less of an impact on things than you imply. I'll still get an Uber/Bolt instead of a taxi 9/10 times, because immoral business practices are still better than immoral & illegal practices backed by a monopoly that you are powerless to change.
