But that's the thing, where can I buy a phone without a locked-down operating system? GrapheneOS on a Google Pixel is basically the only option right now, and this still has problems thanks to hardware attestation in a lot of apps that the ecosystem forces us to use.
This is largely because Apple has dictated the direction of smartphones for the past two decades. All of our expectations for control over our phones are completely out of whack compared to other computers.
Somehow we managed to survive without the majority of society being scammed out of their life savings before Apple came in with the iPhone and locked down iOS, and yet now people are earnestly defending the notion that 90% of people should not even have access to the filesystem on their own device.
