>person you're responding to is suggesting they try the other one of the two top DEs for Linux desktop before leading with "Linux Is Already Broken Before You Even Start"

This is a ridiculous strawman. I empathize with them and want to see accessibility improve (it's something I do in the project I work on even though you wouldn't conventionally expect that blind people can use it). If you're going to talk in such broad terms about the Linux desktop, not just your specific distro/DE, the onus is on you to at minimum try GNOME and KDE. Instead they chose GNOME and MATE, the latter of which is barely maintained and has effectively zero relevance outside of users who abandoned GNOME ages ago during GTK3 or people whose hardware makes the Atari 2600 look like a supercomputer (it looks like the former here). It's not 2017 anymore; Ubuntu with GNOME isn't some near-universal Linux desktop experience. I'm not telling them "nooooo just try my specific config for NixOS bro I promise Linux isn't that bad".

This isn't even to say that KDE will be better; I don't know, which is why I wish they covered it. If KDE is also bad, then this is a stronger argument that Linux desktop contributors need more awareness of and focus on accessibility. If it's just mediocre, KDE devs can see it and learn how to improve. If it's good, then GNOME and MATE devs have a lesson in how they can improve.

I don't expect anyone to exhaust every DE on every distro, but when the userbase is so firmly concentrated around GNOME and KDE, I expect you to at minimum include KDE (let alone if you include MATE). You don't have to, but I'm free to criticize your essay if you have such a massive hole in it. If you don't want to try KDE, literally just find+replace "Linux" to "GNOME/MATE" and solve the problem that way.
