This is much more negative then for Apple then google. Google subsidizes their (far less profitable) app ecosystem by selling user data in the form of advertisements. While there is language about Google having to share marketing response rates, it doesn't prohibit this practice.

Apple on the other hand makes their money by targeting features (privacy, integration, etc) that people pay more for.

Apple will have to transition to a more ad-tech focus in order to compete in Europe under this infrastructure.
