I see the situation as being NO different than Politics here in the States, & probably elsewhere.
In this case, the pendulum had swung too far in Apple's favor for too long.
As such, just like in Politics, Backlash should naturally be expected !
Apple's main problem right now isn't the App Store, it's iPhone Unit Sales, which have stalled-out since the 2015 iPhone 6s & 6s+ made their debut.
I mention that because it's the primary reason Apple is trying so hard to hang-onto the App Store !
What used to be their Cash Cow (iPhone sales) has been replaced by a new Cash Cow (the App Store).
But, the App Store is dominated by Game Apps; Apple makes 70% of its App Store Revenue from Game Apps, & that 70% comes form less than 10% of ALL App Store consumers.
If Apple loses that 10% to third-party websites, Tim Cook's Apple is sunk !
They don't have the right guys running the App Store to make up for such a loss !
There are 18 categories of apps in the App Store, but ONLY Game Apps does well !
I'm NOT a Game App Developer, but this appears to be crystal clear to me.
If Apple loses the Game App portion of the App Store, their market cap gets cut in half !It
