writes "Fedora is going to pay Microsoft to let them distribute a PC operating system. Microsoft is about to move from effectively owning the PC hardware platform to literally owning it. Once Windows 8 is released, hardware manufacturers will be forced to ship machines that refuse to run any software that is not explicitly approved by Microsoft — and that includes competing operating systems like Linux. Technically Fedora didn't have to go down this path. But, as this article explains, they are between a rock and a hard place: if they didn't pay Microsoft to let them onto the PC platform, they would have to explain to their potential users how to mess with firmware settings just to install the OS. How long before circumventing the secure boot mechanism is considered a DMCA violation and a felony?"
Note that the author says this is likely, but that the entire plan is not yet "set in stone."
