My impression was that people responded favorably to flat design. Look at the web as a whole and you can see that much if not most of it is embracing flat design. Sure there was backlash for it, but skeumorphism also had tons of backlash as well.
The thing that I have noticed about the iOS 7 feedback is that people think that Apple implemented a flat design in a very ugly way. Maybe it's because they're behind the curve because they're late to the party. Maybe it'll get better, but everything I've heard so far is about the poor use of colors, gradients, and unnecessarily noisy effects, not about flat design being bad.
