It's Windows XP's 20th birthday and way too many still use it

If my XP system hadn't died (and I didn't have the time or inclination to find and fix the issue), I would probably still be using it for all of the software that I had on it that simply doesn't work on win10. I wasn't going to buy more software just to run win10. I had win7 on a netbook, completely skipped, Vista, win8, win8.1 and it looks like I won't be using win11 anytime soon.
Some of us like the sharp edge of the knife and some prefer the dull side. 
Nothing to do with sharp or dull, culling a perfectly good system loaded with software that won't run on win10. And a system that runs just fine under XP but would be likely to suffer under the load. All in all a high cost impact, which is no doubt why many stuck with their XP OS and computer.
So it has zero to do with which edge you want on your knife, but how much said knife is going to cost and that decision lies squarely with the user
