It would be largely fine, but be careful. Being immutable, a lot of things that you would expect will work differently or not at all. I would not recommend it, but if you’re in for a challenge, it’s not bad.

When you press a button on this revolutionary machine, it will automatically left click for you!

On GNOME, I like BlackBox, though Prompt looks promising once it’s stable.

Most of what you said applies to the Linux kernel too. It’s good to have other options, but being popular does not mean something is bad.

That should work, though you may want to look into Framework instead.

.ovh domains are like $2/year, if that helps.

Also, KOReader adds a bunch of extra features and functionality.

Kindles are really hard to root. Use XDA Developers forum for this kind of thing. https://xdaforums.com/t/fire-hd-8-2018-only-unbrick-downgrade-unlock-root.3894256/, which is what that guide is based on, looks like it only works for the 2018 version and seems way more difficult and risky than most ROM installations. Also, that won’t install Linux, just a different Android version.

Honestly, an actual ereader might work out better for you if that’s all you plan to do.

You can’t do that. Installing custom ROMs on Android devices is very different than installing an OS on a desktop/laptop. Most devices don’t allow changing the OS at all, most of the ones that do don’t have any Linux builds, and then you’ll be stuck with whatever distro you’re given (probably UBPorts or maybe PostmarketOS) rather than choosing your own.

I think their RSS feed has a placeholder title for this.

Yes. Why?

Correct, but new users don’t want to need the command line for something as simple as installing packages.

That should work. One of the benefits of Wayland is that it’s better at scaling than X11. What version of KDE are you running? Is there a switch between two different types of scaling (one is blurry for XWayland applications but works for all of them, the other is sharp for all applications but only some XWayland applications and all Wayland applications work)?

Including non-binary people was not the problem. Relevant quote:

“AnitaB.org, the nonprofit that runs the conference, said there was “an increase in participation of self-identifying males” at this year’s event. The nonprofit says it believes allyship from men is important and noted it cannot ban men from attending due to federal nondiscrimination protections in the US.”

They identified as male, not non-binary, and the event allowed men to come.

Pretty much anything with XFCE, LXDE/LXQt, Cinnamon, MATE, a window manager like Sway or i3, or probably some others I’m forgetting, will work just fine. GNOME and KDE are the most popular but the slowest, and from what I remember, Deepin, Budgie, and Pantheon are somewhat slow.

I’m not them, but I’ll give my reasons. Compared to Ubuntu or Linux Mint, Fedora is more up-to-date, I like the default desktop more, and it uses a method of installing applications called “Flatpak,” which I like more than Ubuntu’s “Snap.” (Snap can be removed on Ubuntu, but Fedora’s default setup is closer to what I want.) Compared to other distros, it is more polished and consistent, largely due to it being backed by a large company. Fedora is really good for both power users and beginners, but being up-to-date can sometimes lead to bugs or incompatibilities, and the default desktop (GNOME) can be hard to adjust to. As a result, I would recommend Linux Mint as a good option for you.
