"Ignoring regulations" in this context basically boils down to "competing with taxi cartels". That's obviously upsetting to the cartels, and unhappy noises are made about background checks and meters, as if those potential problems could only be solved with a cartel.

We both know that Uber & Lyft drivers give better service overall than taxi drivers overall. That's because Uber and Lyft are not part of a cartel, and have to therefore please their customers lest they lose them.
