Banning companies which subvert or break laws or regulations to gain competitive edge over those who follow laws and regulations is not and should not be controversial.

More like: "Uber should follow the same laws as other companies that want to operate in Europe".

I hope they do, since I consider the system far superior to traditional cabs, and would probably still use it if they had higher fares.

I don't see how classifying Uber as a minicab firm amounts to banning it?
