@vadorovsky @eloquence You could apply similar arguments against calling the whole system "Linux". You have choice between Linux & BSD kernels!
Personally I tend to refer to the distros by their names dropping the "Linux" part where relevant. Or for my purposes I find "free desktops" a good generalization, though it may not reflect what others are interested in.
Interestingly: Why we started using the metonym "Linux" is because GNU was a victim of their own success, not worth mentioning.
