I 100% agree, its best to just stick to upstream Fedora imo. Glad you made this comment. The security issues of Nobara always put me off, especially since basically everything it does can just be applied to regular Fedora. I think Nobara would much better serve as a script or toolkit, similar to Brace, or something along those lines instead of an entire separate OS with the security issues it brings.
They’re mods of the proprietary Discord client, so yeah they don’t meet the criteria. But the mods themselves are open source which is nice.
