1. There is exactly one device sold in the entirety of the US that can have the bootloader locked on a custom rom - ironically, the Google pixel.

2. Bootloader locking matters because many (most?) apps will just refuse to run.

3. Why? Because Google built up the attestation API which severely handicapped those 99.9% of devices from running custom roms.

4. Even on the 0.1%, the Google pixel, it won't pass full attestation - so some really picky apps like banking won't run. Only stock android untouched will run those apps.

It didn't use to be this way 10 years ago.
