I agree, and think the sandboxing of the DRM plugin is a positive step towards more openness as well - the opaque algorithm implementing the DRM can apparently only touch the video streams it's being fed, and a unique identifier generated by the browser. Much better than the current situation of Flash having arbitrary network access and suchlike. In concept, I think it's not too much different from server-side website code being mostly closed source. The only difference is that this component happens to be running on your computer. Also there is prior form for this in similarly open systems, e.g. tainted modules in the Linux kernel, which seem to have turned out okay.
