I've stayed a lot with Sony for the same reason, well that and they still make something smaller than 5" phone.  They're usually good about providing bootloader unlocking, though the last Z5 Compact I got was more of a pain, part of why it's still locked/unrooted, but a longer story.

I wish oneplus would make a not-huge phone, I'd be all over it.

This is specifically why i chose the OnePlus and will be choosing the OnePlus3. Their Rom has very minimal 3rd party applications, and you can unlock your device any time you want to take control. and most if not all the hardware has opensource drivers.
