> I think 90-99% of users only use Browser+Office+Games which could work well in any of the big operating systems.
Linux Desktop evangelists have been saying this sort of thing for about a decade now, only they used to exclude "games" from that list because Linux was so terrible as a game platform. Their constant underestimating of "average computer user" is, in my opinion, one of the big reasons they've completely and utterly failed to make significant headway in the Desktop market.
Just because it works well enough on other platforms doesn't mean that users will switch. Usually they won't. If they know MS Office and MS Windows from work they don't want to use LibreOffice in private. (And MS Office and MS Windows Server is far superior in the business context in many ways.)
I stopped caring what most people use. I prefer to use Linux and OpenSource software in general for myself but I don't push it onto others. It doesn't matter if the market share of Linux is 1%, 10% or 50% as long as it works for me - and it does.
Totally, it always bugs me when people complain that Linux is too technical and fragmented and that this way it'll never be mainstream. Who cares, really. I like having all this choice. In fact I'm using FreeBSD (though it could as well have been Linux) as daily driver because I don't get these kind of choices in mainstream software. I don't care if it never gets big, if it did I probably wouldn't want it anymore.
For example Ubuntu is getting very close to that point already. They stuff lots of stuff in it that I don't want (like snaps) and make them really hard to disable completely. Exactly the kind of thing I left Windows and Mac for (as daily drivers - I still use them for my work)
