I've described elsewhere in thread why switching is not an option for me; Apple has slowly trapped me in their ecosystem of Apple TV, Apple Watch, Macbook, Homepod, my BMW which will only talk to an iOS device, iMessage, HomeKit
They don't provide any external APIs to interact with these products so other platforms/systems could make such a switch less painful.
I feel your pain: Apple slowly lured you into spending thousands of dollars on high-quality products which work smoothly together, and then they went and changed the EULA on you and now you can't install non-App Store software on it!
Only that didn't happen, of course: the rules have always been the rules, you just don't like them.
Which is fine, actually, complain all you want. But the victim act is hilarious. "My luxury car will only talk to an iPhone! I should sue!"
He said only an iPhone will properly display album art on the screen of his luxury car as he drives.
You’re not trapped. Over time switch to another provider. Or all at once.
They sell you a service and device with terms. If you don’t like it, get out of that ecosystem.
Certainly don’t use the power of the federal government. Do you like monopolies? Because that’s how you get monopolies.
