I can offer you one perspective and my opinion. With the advent of W10, users lost control of much of their system: downloads, updates, collection of data I might not appreciate, and so on. It isn't so much about W10 but the different stance and approach MS has taken. I have long objected to the MS attitude that we (MS) know what's best for you. Or, in other words, you do what you're told sonny, never mind about your own ideas.
That has occasioned me to stick with W7, probably forever.
