while i definitely love a little push away from ecocidal insanity, this is not the right goal & not the right direction.
manufacturers should be able to do whatever. they can keep devices secure as long as they want, support as long as they please.
but once they stop being the agent of support for a device, right to repair needs to kick in. consumers need to be given the means to run their own software on devices, need to be granted access to the hardware, to the degree they purchased the device under. unlock the bootloaders, provide some kind of modifiable kernel to run the device, and let the world begin to pick up & maintain the post-market rubble left in capitisms wake. right to repair.
