I think this is part of the MS efforts to DRM everything, right down to the hardware/BIOS level.
As far as buying AMD and not Intel, that was Stalman's position when Intel decided not to collaborate on his open BIOS project. I lost a lot of respect for RMS that day. Intel has done a lot for Linux, releasing hardware specs, driver code, and software under GPL. Intel has also contributed to the Linux legal defense fund. Intel didn't knuckle under to SCOG during the end of the discovery phase of the ongoing IBM-SCOG lawsuit.
But Linux isn't RMS's project, so we should all just forget about that and boycott Intel because they won't support RMS's pet project.
RMS is a great man, but sometimes he really needs to be told to go #$%^ himself.
