no.. it's that there's a chance you won't buy, rent, or subscribe to any media through their store or one operated by one of their partners.. it's all about the money.. google's money, they don't give a shit about piracy, exactly.. they don't want you playing local content at all, legit or not, when there's perfectly good pay-for media available through the device for which google gets their cut.
NFL CEO: "... phone rings
NFL CEO: Hey Schmidt, what is this crap I hear that your device is an illegal circumvention device designed to steal money from me, but obeying my wishes to rip off consumers!
Schmidt: Google Cast is just a simple device to enable streaming. It is not different than someone using a webcam and uploading their own videos to where ever he or she wants.
NFL CEO: What?! This could pirated content and would mean I can't fucking scalp my users at the stadiums! My shareholders will have a fucking fit. Fix it now!
NFL CEO: SCHMIDT!!! You know it would be a shame if somehow we used DRM flags in our content to make your device useless. Under the DMCA your device must obey our shareholder wishes. I have friends in CNN, NBC, Universal, and others who would happily make your device useless. I guess we can work with Apple and Microsoft instead. They too understand the meaning of protected intellectual property.
Schmidt: Oh yes oh great masters. We would never want to make the great cartel of the MPAA and NFL unhappy. We want to build a successful relationship
NFL CEO: Grins. Ok very good then. Do what you need to do then to make it happen. FYI how would you like some private rooms at the SuperBowl next year for your family for being so nice to us?
Google is not the evil one here but, but the broadcasters. Remember the NFL with every media mongul on the planet wrote the DMCA and just had the senators approve it and rubber stamp it!
If Google will not play nice and suck it then they will use the DMCA and DRM to ban the device and will sue and arrest any Google developer who wont obey them. This my friends is why we opposed the DMCA back in 2000. If you didn't write your senators back then tough shit you deserved this law for not standing up to yourself.
Until Google is powerful enough to make its own content the content owners have IP laws, DMCA, and use monopoly powers over companies like Google. A ruined relationship with them is death. Microsoft would happily comply if Google wont and then people will bitch and whine how the Chromecast wont stream their favorite football games.
