It is about Microsoft. They also had tons of reasons not implement SVG because SilverLight was better and SVG had flaws according to Microsoft... until they added it to IE9 because it was turning popular. They'll try the same with WebGL, this is typical Microsoft behavior. Microsoft is not the only party criticizing WebGL and the motives of any such party are a separate issue. The technical problems with WebGL have been made clear and appeasing Microsoft or questioning their motives does not address those problems. They said they will improve the specs to fix the issue. What else do you want? Who said they will improve the specs and in what way? There are fixes for specific bugs, like cross-domain image loading. ARB_robustness is in the works, which is an implementation detail that might help somewhat. But I've seen nothing that claims to fix issues of the sort mentioned by Microsoft, just claims that they aren't really a problem. And if WebGL is being fixed then why is it enabled in production browsers today?
