I think the web or HTML5 is the most closed platform ever. Let me explain. You want to program for the web? Javascript. You want to do 3D? we have you covered, you can only use webgl. Don't like it? Sorry but we need to remain open! want audio? We have an API for that, why would you want to use something else? use Audio API, it's open. can you imagine if linux, or microsoft windows or OS X only understood one programming language? Or if DirectX were the only 3D thing you can use? or if to use audio, you had no choice but to use one library? The web is just that, and no, being available on all the platforms does not make it an open platform. It's one big closed transparent prison available everywhere. Once you go in, you are stuck with the onboard equipment.
