I use Windows 10 on my main computer. It's just an OS; my self-respect and masculinity (or lack thereof) aren't in any way linked to whatever software I've installed on my PC.
I don't know where you got the idea that the parent poster thinks new software is magically more stable than old software, as the poster didn't make any claims about the relative stability of Windows 10 and 7.
Btw, what exactly do you do in order to "keep MS accountable" on your machines? I'm not even sure what keeping MS accountable really means here. (Possibly because English isn't my first language and I'm not very familiar with that expression in this context.)
