Chrome dev on WebGL security and Microsoft bullshit
He has some good points and I like the description of safe-ish implementation of webgl in chrome. But I think the main point he misses with the Silverlight/Flash comparison is manageability from a security point of view. Running a plugin is different from using a feature in the browser - people often disable the plugins and are conscious about plugins being an attack surface so the admins often deploy policies disabling use of plugins.
