You must have missed the top comment where it was stated that publishers need to agree to have their games on GFN. Activision not only told Nvidia that it was okay to put their game on GFN, they likely had developers work with Nvidia to iron out any issues in creating the VM that it uses.
Wine/proton are unauthorized tools - most publishers don’t care, and some even encourage it and help to fix issues (i.e., No Man’s Sky), but it’s still not officially agreed to like GFN.
