Being able to unlock the bootloader of a device you own should be legally mandated. I own the hardware, I should own the functionality of it too. I can get the modem being illegal to modify, since that has a ton of regulatory and public safety tape around it, but the OS being irreplacible is dumb.
Also, unlocking the bootloader should be as simple as sending a command to the device. Screw this trend of needing unlock codes (looking at you Motorola, Fairphone, and Co.).
