It always annoys me when people talk about "stuff" without thinking for a moment what the "stuff" actually is. What do you mean by "they don't own H.264"? What does "H.264" mean in your sentence? H.264 is a standard that defines how to decode an elementary video stream. You can't "own it". You can own rights to an implementation — but that's where things get interesting. There are many H.264 decoders, some of which are open source and could be used by Adobe. So their argument is rather weak.
