I mean think about it: people at Microsoft aren't idiots. There's no way in hell that they didn't realize people hated Metro. So why would they still force it upon people even though it means they know people would hate Windows that way?

The only reason is if there is an overriding goal worth the short-term loss of money, and this is the most plausible explanation I could come up with: even if you make people hate your product, if you can force them to move onto a subscription model, they probably won't be able to go back.
