Not sure how things went down in the rest of the world... but in the Netherlands...
People didn't share their own opinion. They just repeated what every one else said.
A lot of people complaining about the missing start menu actually never used the start menu, they started all their programs from the desktop.
People were just stating stuff without thinking. "Windows 8 is only made for touch screen devices"
And then the list....oh...the list...
Windows XP good
Windows Vista bad
Windows 7 good
Windows 8 bad
Windows 10 good
Etc...
I think they even miss Windows ME in that. And (whatever suits their needs) sometimes NT versions are included and other times they're not.
It was quite a drastic change, but if you adopted the new system and made using it into a habit, it was way better than what Windows 10 was!
