To be fair we need a regulation that will force companies to unlock bootloaders when the device hits end of life. But ideally, they should give ability to bring your own bootloader from the start.

I hate regulation, but what else can you do if voting with your wallet doesn't work, as majority of people don't understand the issue or don't care and companies have no incentive to behave responsibly.

They have a great PR machine about carbon neutrality and all that, who is going to notice some old phone destined to a landfill.
