> blocked a direct rail link between CDG and central Paris (my Uber on that route last week cost 99 EUR)
Well, true, there isn't a direct link, but there is a train link, also link to other cities. Last year an Uber from the city center to CDG had a fixed price (if I estimate the fare today it gives me 45Eur for X or 70Eur for UberBerline)
While they do follow taxi regs, I don't see how they aren't "UberX", UberBlack is just called UberBerline here: https://www.uber.com/en-IE/cities/paris/
