It was a lame attempt at humour. But look at your own graph. 7 is ancient, and it's it's incredibly vulnerable. I'll also go so far as to say that graph is like comparing Android to IOS. Sure, there are a LOT of crap systems out there, in poky little shops as POS machines, or China. How about a graph of home users in middle class ( sorry) suburbs where money isn't an issue. See what you get then.
Just so you know, I wouldn't use XP either. But then, I left Windoze behind 17 years ago, and boy do I not miss it.
That said, I can run Windoze XP, 7, and 10 using Parallels. And I never do.
