Maybe this person saw the recent post on HN about Flameshot (and supporting Wayland) and thought "Oh... you can't even take a screenshot on Linux".

I think the best distro for gaming is Pop_OS!. They have a pretty reliable set of software and they also have an NVIDIA version of the distro which is great for newbies. It also comes with Flathub (instead of Snap) by default so latest version of most of the softwares that newbies will use are available (such as Spotify, Slack... and everything else Electron).
