Then you're part of the problem.
If vendors didn't pander to people running IE 5 then they would sack the fuck up and call their nephew to spend 5 minutes installing Teamviewer and Google Chrome.
People who refuse to run modern shit on their hardware may be the majority, but only because assholes are willing to bend over backwards selling them "lazy" as a commodity.
Not sure what the GP is going on about.
In my observations, retiring Windows XP drastically reduced the number of issues from "my stuff doesn't work, it's new, I bought it 10 years ago, why not?" complaints.
There was a small cadre of folks re-installing XP on new machines (I did it too) because there wasn't a reason not to. After Nosebleed and Hearbeep (or whatever) happened last year I shut off old ciphers on all my stuff. And know what? NOBODY NOTICED. I get an occasional hit from China or other shitholes I don't care about trying it, and they often come along with other probes so it's not real traffic.
So the point is, GP isn't correct when he's talking about his "majority," there is no such group. They're gone. The idea that there is a technically adept person running old shit because it still works, who also doesn't know it's risky, and also can't afford to upgrade to new shit is a Venn diagram with three unconnected circles on it.
Go ahead and run what you want as a hobby if you get fulfillment from it. If your hobby puts you at risk, or can't be used somewhere, tough shit.
