Look, Apple does all kinds of terrible things, and I definitely think the government ought to take action against them.
But Apple one time, in 2011, announced that they were going to put in a rule that you couldn't charge a different amount outside the App Store than inside, and when furor erupted, they never implemented the policy. That's it. One time, never actually in practice.
They are still 100% terrible with this nonsense about not being allowed to link to or even mention alternative forms of payment, but let's focus on what they actually do that's bad, rather than what we imagine they might like to do in alternate realities.
Apple is going to force all apps that offer messaging as a feature to integrate with iMessage!
Apple is going to force companies with an iOS app to turn over 30% of their total gross revenue! And it's additive!
If you don't buy an iCloud subscription Apple is going to randomly delete some of your alarms!
