That was probably the dramma about Fedora ending support of 32b libraries, which Steam heavily relies on and won't easily work without.

It's still being discussed, and even if they go through with it (which is a PR suicide for Fedora), it won't be earlier than in two years.

As far as I understand, Bazzite is a version of Universal Blue, which is a fork of Fedora Atomic.

I don't think any of that is disappearing any time soon, though I did read something about Universal Blue no longer autobuilding a bunch of different spins of the system or something. Would that be what you're thinking of?

I expect so, but I also suspect Valve might be waiting for nvidia to get their shit together (or the open source community to do it for them) before making SteamOS officially available on desktop. I just don’t have the bandwidth to troubleshoot or follow developments around it myself
