I think it only highlighted Linux specifically because of the prior tug-of-war there, it mentions right afterward " and other important OSS technologies".
I’d just like to interject for a moment. What you’re refering to as Linux, is in fact, GNU/LInux, or as I’ve recently taken to calling it, GNU plus Linux.
It's a Stallman copypasta, but in this case I think it's justified. The definition of "Linux System" appears to refer to a Linux distribution which would include GNU and countless other projects than just the kernel. Seems like really strange wording since it'll likely just cause confusion and lawsuits down the track.
