Thank you! The worst is when pinch-to-zoom is disabled on an image viewing/sharing page. I believe Twitter is guilty of this. It's idiotic. I've also heard many arguments that responsive design makes pinch-to-zoom unnecessary. A page should automagically adjust so that it's optimal for a 27" monitor, a 2" mobile display, or anything in between. It's a great idea in theory, but I've yet to see it executed well in practice. I guess it's exceedingly difficult to design an effective UI that can automatically and seamlessly scale between a large-format screen and a small-format screen.
