I didn't say 30% fees are immoral, I said 30% fee walled gardens are immoral.

Especially when you make it all but impossible for third parties to operate outside of that walled garden.

EU isn't actually motivated by voting here, because they have power regardless of who votes for them or not. The Parliament "negotiates" with the Commission (executive branch) for this reason - the EU is set up to ensure that decision making is so far removed from voting that it's entirely irrelevant.

The real reason they do this is they perceive it as a free source of income, which they can then use to buy off states to keep them in the EU itself. Note how the rules only apply to really big companies (i.e. US companies), and the fines are really big, and the rules are vague. It'll be a cash cow that avoids upsetting any local interests, the fact they can drape it in pro-consumer clothes is just a bonus from their perspective.
