Oh, I have no disagreement. See, I've had to wrangle with the whole responsive thing recently, and it's a more general rant about the way people perceive it.
There are people who seem to believe that 'responsive' means 'shoe-horn everything down into a mobile size without losing anything'... which of course it doesn't. When you're on a screen that small, you don't want 'all the information you'd normally have'. You want to focus on what's important and hide the rest, but too many people I know seem to believe that 'responsive' means you shouldn't have to compromise on that... which of course it doesn't.
