Why does Apple need to be guaranteed revenue? They sell a really expensive phone. They sell really expensive software, services, entertainment, etc.
Why do they HAVE to receive a tax on everything everyone else does? Because Steve Jobs came up with the phone, the corporation is perpetually entitled to tax us?
Maybe we should have other app stores, so Apple isn't forced to provide free apps?
Maybe websites should be allowed to serve/install apps, instead of being forced to use Apple's, since it's such a burden for them to allow free apps?
Or perhaps no one would want an Apple product if they couldn't access other peoples creations -- like Netflix, etc. maybe Apple isn't the main value if that's the case?
The whole thing is absurd. I've been using software on my Mac for decades without Apple getting a cut. But a phone, oh my, we better all protect Apples TRILLIONS OF DOLLARS from independent developers thinking they deserve anything but a handout.
But you're forgetting this the same for every Android phone, Samsung, tablets, iPads, Smart TV app stores, Amazons Firesticks, Amazon Firetablets, SteamDeck, any device running SteamOS, Playstation, Nintendo Switch, Xbox, Microsoft store, the Meta Quest etc etc
Apple isn't going to change unless the entire industry changes with them, why should they have to do it differently if everyone else doesn't.
Valve set the example (ironically on Mac and PC) that everyone else followed - and trust me as a PC gamer multiple app stores are not a nice experience at all.
