Isn’t that against GPL? You as a user are allowed to do whatever with the software — modify it, redistribute it etc.

The devs could buy a RHEL license and get the sources, which are still under free license, that way.

Here are my two eurocents:

• Fedora Workstation, the main spin of Fedora which uses Gnome, is a very polished experience. I’d use it, if I were a fan of Gnome.
• Fedora Silverblue is an “immutable desktop”, i.e. the operating system is read-only while all user applications isolated from it via flatpaks. It is supposed to make the system more secure, stable, easier to update etc. It’s a cool idea, but I haven’t tried it myself.

Other than that? Not much. As you probably know, most distributions feel pretty much the same, Fedora included.
