Ppl buy Apple products and KNOW AND ACCEPT the limitations when making that purchase.
There are alternatives- get an android phone, there are plenty of brands there.
I buy Apple products ESPECIALLY for the locked down OS.
Why are you against my consumer choice? If any alternative store, payment, in app purchase is introduced - I’m deprived of my choice. And now there isn’t a closed OS I can use.
There are actual reasons I want that OS. My parents had android devices and they got scammed at least once a month to share their details and their cards got stolen as they would download apps and those app would “guide” them how install apps from untrusted sources while promising “enabling free bank transactions access”. After moving to iOS none of that happened. I get the odd subscription I need to cancel but I do that from the phone - not another system.
