Somewhat OT and tin foil hat: I was talking to a friend the other day about whether it was best investing time into getting really good at developing for the web vs native mobile/desktop. My argument was that the big advantage of web dev was that you not only had more choice of backend tools but it was also the best way to get your apps to run on any platform including locked down ones without having to worry about app store policies etc. His counter argument was that the browser is becoming the new target for malware etc especially as the new HTML5 APIs become more sophisticated. He thought that it might be likely that some browser APIs would become locked down by platform vendors. In other words if you want your web app to do stuff like WebGL/Local Storage etc you would need to be explicitly whitelisted by the OS or browser vendor. In which case there could be rules like "your web app cannot do xyz, your website must not have content related to abc". Outright website blocking would seem out of the question, but perhaps things like this are the first sign of a move in that kind of direction?
