See your doing it again by mentioning the 30% market shareYes, and? I don't see any problem with that. Apple doesn't have a monopoly. Google does have a search monopoly, which is why they're being regulated, and for example, won't be able to pay Apple to be the default search anymore. However, I still am strongly of the opinion that Google would be the default even if they didn't pay Apple, because until recently they were far and away the best search engine (and are still are far and away the best free search engine).
Yes - you can complain to Apple that they don't offer a feature, but it should be Apple's decision whether or not they do barring a really good reason (again, health, safety, environmental concerns, etc.). In my opinion "the OS with 30% market share in the EU dares to set its browser as default" doesn't come anywhere close to being "a really good reason", particularly when the resulting regulation actually makes its less-private, massively market leading competitor stronger.
The iphone is getting viewed as a standalone device so when the EU is regulating it that’s what it is doing treating it the way Apple does by not even mentioning the competition
As I believe you are an American then ultimately this isn’t going to affect you because these changes are only happening inside the EU
