Force removal from Mobile App Stores, make EU companies avoid implementing their Pixels or Services or face fines, etc.
2022-2023 for example a lot of companies removed their Analytics and Pixels js, because some EU members agencies (Spain and Italy to be precise) started making pilot cases against domestic companies.
It did work though, EU companies could either take an enourmous cost to properly implement these (ie. by local proxy sending only minimized data) or remove them in favor of EU tracking companies. A lot of similar suits followed with cases against Meta.
By 2023 it was clear the EU would make a political deal with the US so companies restored the defaults, without making the necessary anonymization changes.
