Exactly. And since Google has decided not to indemnify users of WebM, it would be logical to conclude Google's lawyers believe that MPEG-LA likely has a case. Otherwise, why not really get hardware developers on board with indemnity promises?
I'm aware of this. My point being is none of the other hardware vendors know if they're going to get sued until a potential patent submarine fires its torpedoes. Would you want to bet your business by being the first?
