It is unfortunate few devices come with unlockable bootloaders. I take a harder line on that issue; I see it as a malicious decision by the manufacturer and a very strong reason not to pick a particular device.

That's not to say everyone should take that approach; it does involve more effort and demand more knowledge than leaving the OS stock.
