But as has been mentioned a billion times before over the past few weeks... you do have a choice. You can use android or one if its many many forks. You can even create your own, the code is open source. There are also other non IOS and non Android mobile OS’s if you wish. You can buy one of the hundreds of other handsets available from multiple other manufacturers.
I’m not 100% sure, but I even think Xcode allows you to install unsigned apps for 7 days at a time anyway, so even that argument has a potential counterpoint.
Why are you so insanely insistant on Apple charging their way of working? They want a closed system (which by the way has been instilled in Apple by Steve Jobs since the first Mac came about), customers like it like that, what’s it to you? Go for a different product!
