I'm surprised GTK/GNOME has had issues with accessibility deteriorating; it always seemed like they had the best story for it, and I expect Fedora and Ubuntu to care about it. Unfortunately, it's hard to be surprised that if anything would deteriorate, it's accessibility, either.

But while I understand it's not the point of this thread, which is probably mostly venting, maybe it'd be a good idea to focus here on trying to find what can be improved. I'd definitely be willing to sponsor work on improving accessibility in Wayland and Linux in general, patron-style. It'd be nice to have serious effort put into the protocols the way that we are seeing attention put into color profiles and HDR right now.
