Apart from "The taxi model has worked for decades, don't take our livelihoods away" are there any articles on why Uber is actually detrimental?

I find it way easier to use Uber than get Taxis mostly due to the app based "click and collect" model, I would still use that even if it was the same price as a regular taxi. It annoys me that there seems to be lots of "crackdown" on Uber but I don't feel informed enough to know why.
