Hostile to root

I would certainly agree with your use of the word "vehemently" to describe how GrapheneOS developers talk about root access. It honestly makes it really tiring to engage in their community in a meaningful way if you aren't on exactly the same page about every detail, and if you don't have exactly the same threat model as the core developers.

Yes, of course my having root access to my device makes certain types of attacks possible that were previously impossible, but on the other hand it also makes certain other types of attacks impossible that were previously possible. Everyone has a different threat model and the inability to recognize this seems both patronizing and unproductive to me. "Only a Sith deals in absolutes", right?

And if having root access to your device compromises it so severely that it's not even worth discussing, should we all throw our laptops and desktops in the dumpster? Is Linux cancelled because it doesn't have System Integrity Protection like macOS...?
