Remove the BIOS and see whether your system will boot at all.
Remove the CPU microcode and see whether your BIOS will run at all.
Do we get to call it Intel/BIOS/GNU/Linux now?
I think the GNU/ prefix, based on just 8% code contribution, has become largely moot by today. If people want to say "Linux/GNU" then they can do that, but trying to *insist* on the "GNU/Linux" naming based on the rather strained argument that's still all super-important GNU code and the rest is just details is somewhat pathetic.
If the GNU projects wants to gain larger relevance it should contribute more *code* and should be a friendly platform for contributors, instead of aggressively trying to language-lawyer themselves into the naming of other projects ...
