In 2016 you had 2 or 3 AAA games releasing Linux native versions. Now you are lucky if you get a working proton version. Linux has moved backwards. Honestly I think people tried it and hit a lot of problems with it then left. 2016 was the year of the Linux desktop but it failed to capture the market.
One of the biggest problems with Linux is simply additional hard drives. If you fill up your / drive you are basically screwed of you don’t know how to use the command line. Even the easiest Linux distros suffer from this problem. With windows I just reinstall programs to a different drive. With Linux you have to learn about symlinks, create then in the right spot and even then it doesn’t help unless you have a bigger drive. Alternatively you can learn about lvm and combine your drives in to one large monolith but this is even far more work for what’s it’s in Linux literally at worst a 10 minute fix and 0 second if you just install stuff to the right drives.
