It's an interesting angle, the hostility thing. People in the know have largely fallen out of love with Ubuntu but imho that's not necessarily because Ubuntu fell in quality but just because so many "better" things have come up since Ubuntu 04.10. It is definitely a sound choice for non-techy people, maybe more than ever. Personally I'd prefer (almost) any contemporary desktop over Gnome these days, but I can definitely see the appeal for others in terms of simple design language.
Basically you can turn any old laptop into a Chromebook these days using Linux, and most people just like your parents most definitely do not need more than a functional webbrowser. Basically a smartphone with a larger screen and physical keyboard. Even if you don't care about your privacy (or freedom from notification-spam) why still pay the Microsoft-tax.
Does that mean you weren't able to implement those changes or didn't want to regress back from Wayland?
