The fact is that it is poorly designed. The UI is less intuitive, the contrast is bad, nothing goes together except the terrible bright-colour scheme. iOS 6 may be old, but at least it had some consistency.
The average consumer won't have any graphic design knowledge, so chances are lower that they'd complain. I am all for having 'new', I just think this is the wrong 'new' direction to be taking.
That is not a fact. It is an opinion. And many many people disagree with that opinion. Every day that passes, you hear of more and more people saying they wouldn't dream of going back to iOS6.
You might as well stop moaning because iOS6 is toast now. It's not coming back.
