These fuckers don't let you unlock the bootloader, so they can burn for all I care. So far, google have the best record, then oneplus, fairphone and alike (easy to unlock the bootloader, no point or ability to relock with custom keys), then mb xiaomi (beg corporate overlords for the ability to unlock the bootloader on YOUR FUCKING PHONE) and slmsung (loose the option to unlock the bootloader on newer firmware versions, loose security features on older ones), and then huawei/crapple who don't let you unlock the bootloader at all
