Nobody cares about iMessage in Europe, everybody uses WhatsApp or Signal.
A Apple-only messenger doesn't fly in a market where apple has <20% market share
Honestly surprising to me that any application owned by Meta is even allowed in Europe at this point.
Europe is basically a U.S. vassal state, so it shouldn't surprise you.
If this is the case, why is the EU demanding Apple open up iOS? Apple doesn't need EU. The do well enough in China and Japan to cover any meager loss the EU could generate.
Not sure what Europe you're part of but it's way closer than that. And in some European markets, iOS has 60-65% share (like Scandinavia).
Europe as a whole has a 35% market share of iPhones,
Sweden has 55%, tbh that was a surprise to me, but Germany on the other hand is 75% Android...
