Although things like Uber may be a different beast. They basically got big enough that cities were willing to push aside all of these special interest rules that kept the taxi industry crappy. So by dumping their product and acquiring customers, they were able to change the legal environment and infrastructure around them.
But they are also at a huge disadvantage because they changed it for everyone behind them as well. Lyft doesn't have to burn money as fast and gets all the same benefits for scale. Under their current market position, the minute Uber starts raising prices, they die.
