I don't think Windows 10 sucks, in fact I think it has the potential to become one of the best operating systems ever made. Where it all falls apart is the spying issue and the way Microsoft went about doing it. I have been around many Microsoft operating systems and they are all buggy to start with, things will get better with time, its like wine...it matures with age.
Another thing to remember is that the internet is changing and older operating systems are now easier to infect than Windows 10, that's not to say Windows 10 wont get infected. I just think it comes down to privacy with people, but you got to remember, companies have be collecting data for years on us all. So is it such a big deal? Mobiles, Tablets, Computers, Shops, Online Shopping, Email, Census, CV, Job marketing sites, Doctors, Insurance, Google, Sat Navigation, Cars and many many more. Its not a new thing, its just marketing.
It comes down to this, unless you want to live in a bubble or technology free, then you going to have to be a part of it one way or another, moving to Linux will not stop people collecting data, Google have been collecting data from the start, no moans about them.
