Qobuz and 7digital have pretty good libraries and high quality downloads.

That sucks and all, but to be fair this is entirely on you. They sold you a DRM-Free file and you chose to not actually use it and to rely on their servers which you have no control over. This isn't a "DRM Free" issue.
Personal ownership means you take personal responsibility for it.
Fedora Silverblue.
Or really any immutable OS; they would have to go way out of their way to even edit system files, much less break the system. I just recommend Silverblue because gnome is really hard for an inexperienced user to break.
Any real benefits of jailbreaking a Kindle? I mean I know the "You free yourself from amazon!" elevator pitch, but what exactly does that mean?
I can already upload pretty much anything I want to it with Calibre. Can I add support for other ebook formats? Cooler utilities on my Scribe? Alternative ebook stores (yes I know where I am)? A user interface that isn't absolute garbage?
Because it's not "just a fancy interface"?
It makes the entire process from purchase to playing completely painless, on top of a large community of people, guides, achievements, etc. I think I'd maybe improve my performance by like...a fraction of a frame per second. Good trade off.
And as others have mentioned, Lutris does a good job if you don't want steam.
I just wish Wayland weren't so weird about screensavers. It's it so much to ask to be able to lock my account when I have a screensaver activated?*
*This is what I'm told is the issue when it's brought up on KDE, i really don't have the wherewithal to actually dig into it. Could be talking out of my ass on this. Hope I am at least.
Bazzite and Chimera are "SteamOS-like" distros that are more focused on providing a game console like experience.
They're immutable operating systems, and the primary UI is Steam. Definitely usable as a desktop PC but that isn't really their target niche.
Bit of warning about KDE:
It is very customizable, but as a by product is also really easy to completely fuck up. The first time I used it (eons ago) I ended up removing the task bar and couldn't figure out how to bring it back or launch programs.
Just spend a bit of time reading up on it and you'll be fine though.
