Which EU country reacted against Uber's predatory pricing when it was actually happening? Ie. which EU government refused investor money flowing into their economy? The only examples I can find are a few cities, and some of those are in the US. No EU state did, unless I'm missing something.
Sure now that it costs them money, they're reacting, making things worse for literally everyone: the taxi drivers, who've been victimized by the governments not reacting when they should. The customers, who are now paying more. The Uber drivers, who are certainly not the ones getting the money.
A great lawyer will tell you laws don't matter if they're not applied, and then tell you how laws are applied and what you can and can't get away with (this is a necessity since most laws aren't very clear at all, especially where it comes to actual real-world cases or penalties). The EU are absolute masters of that. The famous GPDR, for example, isn't protecting anyone's data in any way it matters since governments have the power to grant themselves exceptions to them. Which lead to all the things the GPDR tried to avoid: insurance getting private medical data (who are mostly part of governments in the EU), private medical data being used by the police or in court, just to give some examples.
Hell, it's now been confirmed every 2 years or so since 2015 that essentially all European countries think all of the FANGs are abusing their market position. Google, Facebook, Amazon, Apple, ... they've given them billions of dollars in fines. Tell me, what has been fixed? US advertising companies are deeper entrenched than ever before (even outside of the internet, ie. ClearChannel). Law is supposed to fix the problems. Well, obviously the problem of US companies' dominance is not solved, in fact it's gotten a lot worse.
And this is nothing new. Take what EU countries signed in the Budapest memorandum. You will find that it states that if Russia ("any of the ... blabla", which includes Russia) takes Crimea a bunch of EU countries (France, UK) would, first, declare war on the country that did it (Russia) and initiate actual hostile action against that country (ie. not just support to Ukraine). That meant they agreed to have UK and French (and ...) soldiers attack Russia. That was the security guarantee Ukraine had, and that was an international treaty, which in the EU (look it up) has the power of law.
As everyone and their grandmother's cat knows, they didn't actually follow through. They "gave support". That's just one, at the moment important, example.
And of course, the effect is the same: it became worse and worse. Russia's actions became worse and worse and worse. Now the EU countries have given the same guarantees for countries like Poland, Latvia and even Estonia, either directly or through NATO. Will Russia attack? Why not? It's not like these countries will (or let's be real: can) actually fight under any circumstance.
