Epic wasn't suing for exclusivity, and though this is being painted as a win for Epic they didn't really win anything yet, they just made google loose. First they didn't sue for damages and won't get anything. The court also outright ruled out forcing google into a lower transaction fee. What happened is google was proven guilty of anti competitive practises and anti thrust violations by bribing and/or forcing developers into exclusivity deals with the play store (which doesn't allow them to publish elsewhere, i.e. an hypothetical android epic store) and also bribing and/or forcing manufacturers to not install concurrent services with the play store and always shipping the play store by default.
This is a win for consumers and I don't get why Epic wasn't able to make Apple loose on this same exact point. The case was different and Epic was suing for damages there but still, it's painfully obvious Apple is an even worse offender when you simply can't publish anything on iOS/iPadOS without going through Apple.
Android/iOS platform ownership doesn't mean anything, anti thrust laws exist for a reason, to avoid massive corporations being able to use their massive power to limit competition, like how there's only 2 mobile operating systems, how amazon owns the majority of the online retail marketspace, how facebook dominates social media and was allowed to buy or handicap most competitors over the years, etc. etc. etc. all examples on how regulators failed at their jobs. App stores are just another place where they're failing, this is a move in the right direction but a very small one.
That's a ridiculous argument, read above.
