Oh no 1gb of space is being used windows users totally care about that as they go from an OS that out of the box takes 100gb to one that takes 30gb. Thats pretending what you said is true because Snap doesnt store 5 versions by default it stores two. Secondly the common runtimes are shared between applications and versions so the amount of extra space when storing multiple versions is minor also distro packaging also stores multiple versions by default 3 if I recall correctly for dnf.

I think the fact that you think a win10 user cares more about an app taking a few seconds longer to open on first load than their GPU driver being unstable(from a new user perspective) is everything. Yes! the driver is nvidia's fault but its also fedora intentionally choosing to not ship it out of the box. Many other distro's do this so nvidia users dont have to go through the hassle of foss drivers and them breaking every kernel update.

Also I dont blame fedora for this, fedora doesnt target new users and as a fedora user I like that they aim to ship a fully foss system and I think they make it easy to include properitary packages if thats something you want. However its pointless to point someone to a distro where you have to then give them a bunch of extra steps to enable basic functionality when there are plenty of distros that work out of the box.

For a new user one of the ublue spins is a good choice. They get the base fedora experience with nvidia gpu's sorted out of the box and flatpak.
