same with apple - "now we'll ignore user-scalable=no and screw every responsive webapp out there"
instead of user punishing badly behaved application, vendor are indiscriminately breaking well behaved apps whether they're doing the right thing or not (ie. apps that use em and thus respect user accessibility settings)
this leaves both developers AND users with a sub-par browser experience - like all canvas games out there now get zoomed on double taps, an animation which is often enough to stress the device gpu so much that the browser crashes.
I'm all for improving the web, but there are ways that work and there's this force feeding crap to developer without tough and foresight, and we as a community need to call what's good and what's crap for what it is.
