While the EU doesn't use a "three strikes" model, they do use progressively higher fines and other consequences for repeat offenses. If Google had ignored the 2017 Google Shopping order, for example, they would have lost a repeat investigation relatively quickly and there would have been very large fines. But instead, they changed how the product works, in a way that looks like they're responding to the decision and trying to follow it.

In a company with as many independent lines of business as Google has it's possible to have multiple instances of anti-trust enforcement that don't look like "we already fined you but you're continuing with the prohibited behavior", and the Android, Ads, and Shopping cases do all look really different. Plus they're covering overlapping time periods, which limits how much the regulator can say "you should have listened to us before".
