Trying installing the default .iso of Fedora workstation or Ubuntu-latest and see all the things Gnome brings along.. Maps, Photos, IM client, even a bundled browser (Evolution or something) that is based on Firefox but dependednt on the few Gnome packagers to keep up to date(instead of just letting the user download Firefox on their own or shipping the latest firefox).
Even Archlinux, if you install Gnome-desktop, you get all the cruft. You need to explicitly find a way to install just the minimal gnome desktop without all its apps.
OpenBSD however, for a server usecase, comes with a very cohesive, sane set of tools carefully maintained by the folks who ship OpenBSD. If anything, they are very conservative about adding stuff to that ecosystem.
The Gnome web browser is based on WebKit (Safari) not Gecko (Firefox): https://en.wikipedia.org/wiki/GNOME_Web
As for myself I got lazy and just use Windows 10. It doesn't enrage me if you turn off all the cloud shit, treat it like a file manager/window manager shell and run all your open source stuff on it. Again that works because there's a clear separation of OS and applications.
When you start mixing the two (hello Linux) it's where you get problems. I think snaps were an attempt to solve some of that (badly).
