I don't get surprise that Gnome's people are the one who are promoting this crap:

"Don't package my software"
"Don't theme my app"
"Don't do this"
The excuse is always the same "because normies want the shit works" but in my opinion this is a red flag because they aim to a model similar than Google's and Apple where they centralized everything in a single repository and have control on everything. A good example is the fucking Mozilla, they prefer flatpak because they can deliver Firefox with their telemetry crap and many distros maintainers just disable by default.
I believe that if you want GNU/Linux to become like Windows or MacOS there is not point to have a "cheaper copy" then I prefer to use the proprietary crap directly. Don't let those people steal your freedom of choose.
