Whatever legislation they face, they will implement it in the most hostile way towards non-Apple services/users/companies. See how they implement off-App Store payments in the Netherlands and/or South Korea. Apple is not giving up on iMessage. And, given the legislation becomes to cumbersome to deal with, they will withdraw from countries - they threatened to withdraw iMessage from the UK already. The EU is already becoming a second-class market for technology companies (see Meta's Threads, and many more will follow).
