Obviously open source will be helped greatly if Linux distros cease to be able to work with most wireless adapters and virtually all modern graphics cards because you can't modify the (apparently desperately boring) firmware: meanwhile, the entirely proprietary competition can keep going, full strength.
I use nothing but free software on my home systems, excepting non-free firmware for which there is no effective replacement, and, y'know what? I think this is preferable than being stuck with Windows because I can't make my graphics card display anything without a few kB of non-free firmware.
