Apple: this is our system and we've always been upfront about it. We're dictators of our ecosystem. You can't compel us to open up. Yes there's less customer choice, but we have a right to say how our own system is run, and we've always made that clear to everybody. Forcing us to open up our system is like forcing Nintendo to allow Microsoft games on the Switch, bypassing paying Nintendo anything.

The courts say fair enough, that's correct.

Google: we claim to have an open ecosystem, but actually we don't. We're using our market position to impose terms on phone makers, if they're big like Samsung we might give them permission to have their own app store, with certain concessions. We have backroom deals not to take revenue from some large companies, but to take it from others. We have power over OEMs and we use it to further consolidate our monopoly. They will agree to our terms because they have no other choice than to comply.

The courts say whoa that seems like an abuse of your dominant market position.

You're looking at it from the perspective of user choice. That's not what the courts care about, they care about the law. The Google case was always more likely to be a win for Epic, despite Reddit and Lemmy not realising it.
