This whole issue is being blown out of the water, Fedora users would be no less free to do what they want to their machines, they only need to disable secure boot. The actions taking place are to help people who don't want to do that, and that is not the kind of person that would boot a custom kernel, or run SystemTap.
The unfortunate reality is that in order to make your distribution work on a machine that was built for Windows 8 without disabling secure boot you will have to do the same thing. I would expect to hear Ubuntu and others to come to the same conclusion.
If the idea of secure boot is to much to deal with just by a computer from a Linux supporting company like EmperorLinux or System76.
