Sorry, but I don’t feel like a guinea pig. I can use an enterprise grade operating system for free (as in beer), I’m free (as in freedom) to study it, adapt it to my needs, and contribute to it.
Please remember that even in Debian or Arch there are companies interested in their good shape (i.e. Canonical and Proxmox in Debian, Valve in Arch).
Fedora actually is a 100% non profit community. Even if the sole sponsor is pretty prominent and well-known to all.
All in all, what is a community? In a community there are volunteers, hobbyists, end users, enthusiasts, layabouts, guitar players, trolls, freeloaders, and also paid people by different stakeholders (companies). Also in the Linux Kernel itself there are paid people working to develop it (even from Microsoft, for those that weren’t already aware of that).
