Hehe... made me smile... but isn't this just Mozilla people winding up Microsoft? It makes a pretty big point of "just like WebGL". I doubt this will make Microsoft say "oh look they were right about WebGL, we'd better implement it now". Everyone knows Microsoft want to promote DirectX over OpenGL, and the legitimate-but-not-unsolvable security issues in WebGL serve as a nice excuse.
This is more than just a wind-up: it shows that Microsoft can't attack WebGL on one hand and push Silverlight w/shaders on the other. This puts pressure on them to come up with a consistent message.
Did any of the Microsoft-bashers here even read the article? Microsoft responds in the comments and says the issue is already fixed in internal builds and will ship with Silverlight 5 RTM.
