I'm pretty sure that Jason would no longer stand by that statement-- he was simply blowing off steam there. I think that we have a good working relationship with him. It's a bit unfortunate that every comment one of makes on an obscure forum or mailing list will forever be quoted as some kind of official statement.
The comparison he did with VP8 wasn't unfair but it is important to understand it for what it is: A comparison between something very mature and well developed with something very new and raw. Even given that VP8 did reasonably well- it was quite competitive with x264's baseline profile encode.
