There's nothing inherently illegal about monopolies, just anti-competitive behavior. While Apple is engaging in clear anti-competitive behavior (eg shoving the app store down customers throats), they've reined in restrictions of competing browsers so that they're actually worth using now.

What do you call the Apple store then if it's not a monopolization of the iOS ecosystem?

This article accurately captures all tech monopolies, Apple included.

Well in the one legal case Epic vs Apple, the judge said it was nonsensical to say that Apple had a monopoly on its own product.

Judges get decisions wrong all the time.

Can't you apply the exact same logic to Google and Google's services being bundled together? The bundle is their product; nobody's forcing anybody to use the Google services bundle, but you're certainly at a disadvantage if you don't - the exact same - as with Apple, not using their provided APIs/following their ridiculous rules/not upsetting daddy or he'll take your app away is the exact same thing.

Probably worse so as Google don't seem to copy the features of companies and then spin them as their own all the time like Apple gets away with. Or to kill/remove/restrict competing apps when Apple decides to get into the market for something, or just generally as a "punishment" for not following Apple's strict rules (that only exist to benefit Apple, whilst they tell consumers "it's all 4 u baby").
