Well yeah... the App Store is the only way to distribute apps on iOS... and it's been like that for 12 years.
Why is this suddenly a problem?
If developers don't like Apple's rules... why did they put their apps on Apple's App Store? And why are they still there? Why don't they abandon iOS altogether and try their hand at the other app stores from Google, Samsung, Huawei, Honor, etc?
Oh wait... is it because the iOS App Store is actually very successful for developers? And they can still make tons of money from iOS even though Android has twice as many users?
I'd rather get 70% of something than 0% of nothing.
People can buy apps for as little as $1... or they can get them for free. So I don't see what "competition" will do to the consumer app market.
And if we're talking about developers... there are no better deals to be found on Android despite there being multiple app stores. The Samsung app store takes 30%... and the Amazon app store takes 30% too. And we know Google takes their 30%.
So even though Android has "competing" app stores... apparently it's not the magic bullet you think it is.
