I think there is one quite simple aspect that both Monty and reporting around WebRTC misses in general: there are actors involved who fear WebRTC itself, because well-working WebRTC will hurt their business. The "war" of VPx vs. h264 is just a tool to postpone working WebRTC.

The quite obvious name is Microsoft (with Skype and Nokia). Apple and Cisco also seem to benefit from stalled standard. Google is only one that has would benefit. Mozilla perhaps too, but Mozilla is just a browser, with no weight in the matter.
