If “nearly every app” that people already use suddenly has a big warning on it, people will quickly decide the warnings are meaningless and start ignoring them, like Prop 65 warnings. Congratulations, we’ve moved the needle backwards.
You have to meet people where they’re at. I finally switched to Linux when MS introduced a feature I wanted no part in (Recall AI), but I would have given up within a day or two if the transition hadn’t been basically seamless. I was able to pick up right where I left off, using all the same apps I did on Windows except MusicBee RIP, but now I’m in a better position than before, on an open-source OS instead of closed-source. Now there’s a little less friction between me and better, freer software.
The ELI5 for Fedora’s atomic desktops is that if Windows had an Atomic Desktop version, Program Files and most of the Windows folder would be read only, and each program you installed yourself would go into its own folder in your user directory. That’s the basic idea. It’s harder to screw up an Atomic system as long as you stick to containerized app formats like flatpak/appimage whenever possible. It makes it easier for everyone to diagnose problems, and easier for users to roll back if an update has problems. Even if you were to install it right now, you could use one simple command to “roll back” to any image from the last three months.
The benefit of Bazzite is you have all of the above, plus a lot of gaming-related stuff preinstalled which, if you were to install them yourself in a normal Fedora environment, you’d likely have to spend a lot of time just learning how they’re supposed to be configured, how they interact, which versions have problems, and how to troubleshoot problems when an update to one app breaks a prerequisite for something else; eventually you end up in config hell instead of actually using your computer. With Bazzite, the image maintainers are the ones in config hell - they work out the kinks, app versioning, communicate with upstream to fix issues, all that, so your system should be in the most functional state that a Linux system can be, so you only have to think about using your apps.
