People have gotten it into their heads that Windows Vista and Windows 8 were
the "bad" ones, while Windows 7 and Windows 10 are the "good ones". For
Windows 7, it's because it was basically just Windows Vista without the
popularly perceived problems (coming too early, being put on hardware that
couldn't handle it well). For Windows 10, it's because the Start Menu
returned, or something like that.
Keep in mind that Windows 7 was the worst one at the point it was released,
too. Microsoft is gradually getting people used to a design that attacks them
more, and the outrage people are having over trivial little things like the
Start screen are only helping to distract people from it, though it's
probably not intentional. Because people hated Windows 8, Microsoft can say,
"Hey, people who hate Windows 8! We're sorry we made such a huge design
mistake, and we've fixed it in Windows 10, so come along!"
Just an example of why caring about your freedom is important.
