It was a problem before IMs on phones. Or smart phone. (Maybe not IMs because of IRC). Microsoft have been conflating monopolies with standards since forever. Not only dominating desktop operating systems, but office software on it. Using monopoly of one to get a monopoly of the other. And lets not forget what they did with browers. The EU is only body in the world dealing with the problem at all.

Phones in Asia sound even more dystopian than here in the UK. Surely you can still go LineageOS, GrapheneOS, etc?
