flash and silverlight have gone trough an evolution where they are obligated to respect a users privacy and not to allow doing arbitrary things (like installing a rootkit on a machine) because of that. The DRM plugins being more or less directly supplied by the MPAA have no restriction or expectation whatsoever. Users can't execute arbitrary code on them (maybe) but the providers of the plugin can very well install rootkits on your machine, and they're not obligated to give a user any control over the privacy and inner working of the plugin.
