Yep, the app store is also very profitable for them so they can afford to have this go to the courts. They want the minimum amount of regulation possible, so they first lobby the regulators to apply as little regulation as possible and that the regulation that is applied is as vague as possible.
Then when it comes time for implementation, they make an implementation that isn't exactly 100% in accordance with the regulation and wait to be taken to court. Then they get to argue with a judge related to what is and isn't in accordance with the regulation. If they get lucky, the judge will rule partly to them, which gives them less strict regulation.
The EU lawmakers can then re-vamp the law to make it stricter, and the process continues again.
