To combat this I think drivers, firmware, etc. should be acknowledged as being in the same category as spare parts, manuals, repair tools, etc. They are equally as vital to being able to repair your device, and therefore should be open sourced at the latest when a manufacturer pulls support. Of course I would prefer them to be open sourced immediately, but with how software IP works currently that seems like a pipe dream, especially for devices with very complex drivers, like GPU’s.
