Sorry how else are they supposed to do it at Uber scale?
Disclaimer: I briefly worked for Uber and quit in disgust
That's because American tech doesn't pay its fair share of taxes to the EU compared to its revenue.
The people at Uber are ubersmart, so they can figure it out. If they can't, they don't know how to run their business in line with the law and should be fired.
I swear this is like a restaurant chain complaining that they shouldn't be required to follow foodservice regulations because of how much money it costs them at scale.
Anyway, if they're so large and special then they can hire a bunch of people. Large scale should make it easier.
