There are many reasons to dislike Nvidia on Linux. Here is a little thing that bugs me all the time, the updates. Normally the system updates would be quick and fast, but with the proprietary drivers of Nvidia involved, it gets quiet slow process. And I am not even talking about any other problem I encounter, just about the updates.
As an Archlinux based system user (EndeavourOS to be precise), I get new Kernel updates all the time. That means every time a new Kernel version is installed, the Nvidia driver DKMS has to be installed too. And that is basically the slowest part. But that's not too bad, even though it's doing this twice for each Kernel I have once.
What's more infuriating is, if you also happen to use Flatpaks for a very few applications. I really don't have many Flatpaks at all. Yet, the Nvidia drivers are installed in 7 versions or what?! And they are full downloads, each 340 MB or more. This takes ages and is the only part that takes long to update Flatpak system. I always do flatpak remove --unused to make sure nothing useless is present. /RANT (EDIT: Just typos corrected.)
I'm not new to Linux, I know what arch is. And Debian isnt the only alternative to arch. Like I said every Major distribution has community repositories.
Ubuntu has packstall, Fedora rpm fusion, opensuse probably has some aswell, void has community repositories in xbps. And guess what they are all pretty up to date.
I'm not going to install a Linux distro based on the community repository, I'm not even running any of the major distro, because I don't care what packages are available. I have a few programs that I run, and it's not that hard to make other programs work, when you know what to do.
