The last time I touched GNOME (or any other Linux desktop environment) was in the mid to late 00's.
While the specifics of the problems you are seeing may be different, the substance of the issue remains the same. I can't speak to the specifics of the GNOME development community or what's going on there.
But the end product always was - and apparently, still is - a totally unusable pile of garbage. I would take a clean install of Linux, install GNOME from package manager, and it just would not work without tweaking and poking and prodding. Once I did, it was inconsistent and buggy and crash-prone.
It's sad that 15 years later, despite the massive resources put into this project by big players with capable engineering teams (Red Hat, Google, etc.), the situation remains largely the same.
I note that the other commenters are picking at specifics of individual statements, and not the overall whole. When someone argues against the examples and not the big picture, that tells the story right there. Those are the same kinds of folks who will say "works on my machine with version 3.45.1.89a build 19283 of the widget lib, so clearly this is a non-issue for everyone, go away".
