Man that would be amazing. I don't see that ever happening, but it would be great to not be stuck with hardware that is unusable or near unusable because the manufacturer abandoned it or went under. Though it would be important that all functionality be able to remain intact if they hand over the tools. In the most technical sense the hardware is still usable even if you have to write new firmware from scratch, but practically it's useless without having something to work from and enhance/bugfix.
