And I'm fine with you wanting root on the device you own. But you were implying that not having root means that you don't own your device. I disagree with that. You can totally own your device and not be root.

I think it is important, because I read a lot of comments that imply that "owning their device" means "owning the developers". And that's a wrong fight.

The real fight is that it should be illegal to prevent me from installing my preferred OS on a general-purpose computer.

Fair enough. Owning means having a choice. The unlockable bootloader enables that. But for me the choice of OS will be one that lets me access all files on the device should I need to.
