That's a good thing, no? That's why we want to have a competition. If Apple wants to keep the developers, they have to lower the fees.
I don’t think Apple particularly cares. They survived the absence of Fortnite on iOS after all.
Instead, the ones being inconvenienced are the consumers, who have to install a third party App Store just to access an app which has no reason not being in the App Store (it doesn’t make use of banned APIs or feature controversial content; Epic is simply trying to incentivise users to download their App Store).
This has nothing to do with competition, and Epic is not the hero of their own story. Epic has never been in this to empower developers or benefit consumers (how exactly are the latter better off from having to access Fortnite via third party App Store vs simply adhering to iOS app store rules and keeping said app available.
The irony in calling us Apple sheep. You were all but pawns then in Epic’s very public spat with Apple, just as you are all pawns now. Your promised utopia will not come.
