Xiaomi won't give Android updates if you unlock your bootloader

"To protect the device’s security, avoid data leakage, and provide users with a more secure and stable user experience, bootloader unlocking will be disabled by default on Xiaomi HyperOS."

Avoid data leak my arse, stable user experience? They must be high. Users are the first line of security and why do they care when they had already made sale. HyperOutrageousShite. I bet some of their employees had root binaries on their device.
