I've no idea why so many people expect completely different Unix-clones with completely different origins that simply share one component between them, which they also all heavily modify, to somehow give up their own identity and merge. It's probably simply because others all call them “Linux”, but they rarely even call themselves that. One cannot easily find the word “Linux” on the websites of “Fedora” or “Ubuntu” for instance and they simply call themselves that.
