yeah, but the thing is, compliance with other EU legislation (eg. GDPR) usually just gets implemented world-wide, because it wouldn't be worth the development time it takes to implement *another* layer restricting that implementation's scope
It's weird how legislation designed to curb anti-competitive behaviour helps a completely different corporation become anti-competitive. Safari/WebKit is one of the few Apple products I'd love to stay somewhat dominant and relevant - not for Apple's sake, but for the browser market as a whole.
