Wait times are as high as 2 months (depending on how old the phone model is, etc...), and even as a regular Xiaomi customer, their support never seem to allow anyone to skip the wait, even if for example they broke their old phone and want to set up a new one like the old one (ask me how I know). During that period, MIUI is like a data collection honeypot, sucking up your PII and serving you ads.

It might be 'normal' now to Xiaomi customers to wait to be able to unlock the phones that they have paid for and own (perhaps in the same sense someone in an abusive relationship might consider getting hit 'normal' because it has been happening for a while), but the idea that the company who sold you the phone gets some say on when you get the 'privilege' of running what you like on it, and make you jump through frustrating hoops to control your own device, is certainly not okay.

If they just wanted to stop reselling phones with non-Xiaomi sanctioned malware / bloatware added, making the bootloader make it clear it is unlocked (as Google does, for example) would be enough. Or they could make a different brand for phones that are unlocked, using the same hardware except with a different logo, and let people choose if they want unlocked or walled garden.

However, they make money off selling targeted ads based on information they collect - so I'm sure that they probably don't want to do any of those things if they don't have to, because they might disrupt their surveillance capitalism.
