Software freedom is about freedom of choice, not philosophically mandated security holes. You are free to take the GrapheneOS code and introduce a huge vulnerability in the form of a privilege escalation path from sandboxed apps if you wish, it is open source and you can easily compile and flash your own build.
Mobile phones store incredibly intimate data and are incredibly vulnerable to seizure. It stores my message history, pictures I've taken, so many other records that together would provide an incredibly detailed view into my private life. And it is on my person at all times, even through checkpoints where I have minimal protections against search and seizure like borders! This is not a device that I want a broad surface for modification of system software on.

So you're arguing the same technofascist arguments that Apple and Google both claim. I own my phone, not technofascist sky daddy, or whatever developer also envisions that role.
My hardware. My rules. More people like you need to learn what ownership actually bloody means.
Why is providing a mechanism to view your own data a security risk? You cannot view application data (even in a read only fashion) without root on android. Why should the app be able to read its own data, but the human not able to?
