I think what some people fail to realize is that this is an open *hardware* solution. Intel's FOSS drivers are very nice (I use them myself), but that is distinct from the hardware itself being open. Things like this are actually extremely useful for security purposes, as it allows hardware-level DDC (Diverse Double Compiling, used to counter the Trusting Trust attack most famously explained by Ken Tompson), and in general allows for much more thorough security auditing at a hardware level. The other useful aspect is that it would be fully free and therefore could be customized for different purposes. It's not going to be replacing gaming hardware, but it's at least a baseline for security and research purposes.
