If i'm not mistaken I don't think that Fedora will be affected because Fedora is upstream from RHEL. Now distros such as Alma, Rocky, and EuroLinux may be affected because they are downstream from RHEL. But I can be wrong.

I'm using LibreOffice at the moment.

There are several options. Alma/Rocky, Fedora, Debian, BSD, just to name a few.

I don't want to spoil the video if no one has seen it, but all i got to say is one word: Malevolent.
