Keeping track of companies that "care about your data 🥺"
Over the past few years, a suspicious number of companies have started to "take care of your data", aka block/strictly limit your ability to unlock the bootloader on your own devices.

If you know of specific details/unlocking methods, please PR them or drop them in the discussions
Caution
Reminder that no matter how nice a company is,
you should not trust them unless their unlock process is 100% offline!
