Lab rats is a strong term (not wrong by any means) but people seem to forget that Red Hat is also one of the big players trying to make Desktop Linux better. And when Fedora users report bugs to Red Hat, they fix the bugs not only for themselves, but for the entire Linux Desktop community (they are large contributors to the GNOME Project, as well as making efforts to make Wayland better). Their decisions as a company may be causing community backlash, but without those big players (Canonical, SUSE, Red Hat) Desktop Linux wouldn’t be nearly as good as it is today. I see Fedora as a Debian, but company-backed (say what you want about this statement, but the Fedora desktop experience has been the same for a while, and will not change any time soon.) Fedora is also a Project, not a Product. A distinction that Red Hat takes seriously. Fedora is not profitable to Red Hat (the bug-fixes, as I stated above, benefits everyone in the Linux community, not Red Hat alone), that’s why it’s 100% free (both as in freedom and as in beer). Also, they have full-time employees working on GNOME and Wayland
