Interesting that you call MPEG-LA scum, while Google _is_ _actually_ suing Microsoft over the use of h.264, right here, right now. So who is the scum?
I wasn't aware of that. Hmmm. It's one thing to sue for patent infringement, but what MPEG-LA did was IMHO much worse. Not the creation of the H264 patent pool or its licensing, but their attempt (solicitation) to create a patent pool specifically to use against WebM. It's one thing to patent some stuff, use it, and defend it. It's entirely different to see a competitor, try to get people to gang up on them with a patent pool covering their thing, and go after them. OK, if it's patented that wouldn't really be "their thing" (googles thing) but MPEG-LA had no stake in VP8 when they went after it. That is why I called them scum. I'm not certain but I think there are legal terms that cover that behaviour as well (cartel, collusion, and possibly racketeering might be applicable but IANAL).
Now if you tell me Google sued MS over a patent they purchased just to sue, I may have to include them under the scum umbrella.
