You don't really own your #Xiaomi devices. You have to take permission from the company and have to wait for several days to unlock your device. And I thought Facebook account deletion was bad.
If Xiaomi is going to unlock my phone and not me, I can be sure that they are going to put backdoors and malware into the phone.

Some people had to wait for 1440 hours!

Meanwhile #Huawei doesn't even permit unlocking the bootloader.
