@Seirdy Yeah, the term basically exists because RMS likes getting credit for things, as far as I can tell. There isn't an argument for it in modern linuxes. As for what's a GNU/linux as people use the term, I think it's basically synonymous with "linux distribution" (or meta-distribution), maybe with the added specification that it should contain primarily free software or separate free and non-free into different repositories.
I like "linux distributions" or just "linux" better.
