This is such an anti-consumer move, by refusing to unlock the bootloader Asus hinders the ability of users to extend their devices' life beyond Asus's original support window by flashing alternative ROMs...
I'd like to see right to repair laws expanded to right to unlock. I think you could make a reasonable argument that a working device that's not receiving security updates is just as broken as a device that's experienced a hardware failure.
As much as I agree, I don't think our legislators are knowledgable enough to be able to handle the issue, and majority of the users don't care enough to push for something like this. This isn't like USB-C vs Lightning where users are sick of buying cables and chargers, so the issue is much more visible.
