This is not an accurate depiction. All those parts look like they will fit out of the box and all the parts are there.
Little do they known that both Clone Hero and YARG are native, the old crummy PC ports run fine on Wine (Even the WTDE mod) and RPCS3 works fantastic for Rock Band
Most of the list is either websites or websites on steroids (Electron), it's more than sufficient for "everyday users", but it doesn't really say anything new about the state of the Linux desktop, it's been like this for a few years in that aspect, but it has progressed a lot as of recent on many other aspects which are worth making a notice about.
On the other hand I think it's important to mention those things we don't have or can't ever (or who knows when) have, because the companies behind those products don't care at all for the platform, or care about in a negative way, several of those are used by "everyday users" and I'm sure it can be a deal breaker for them. I guess it's a decent campaign to cater to those looking at their options with the incoming end of Windows support at leastZero-setup snapshotting, GUIs for system settings, more sophisticated repo management, less custom-patching of software, more utilitarian than minimalist.
