What are you smoking?

The only reason I've ever unlocked a bootloader has been to replace the OS with a different one. And it had nothing to do with rooting. I have no interest in having a rooted phone on my person at all times. But I have full interest in having GrapheneOS protecting me, among many other things, from opportunistic government spying.
