What points? That Android itself being open doesn't guarantee that every piece of software, every piece of hardware, and every carrier is going to be totally open?

That's an asinine, utterly idiotic argument. It's a juvenile strawman ("Gosh, and I thought Android was open...but look I can't install Skype on my Sprint phone").

MG Siegler has seldom said anything that had any merit or added to the argument in any meaningful way. Which isn't a suprise, as TechCrunch is a trollbait emporium: They know that posting such asinine nonsense gets them hits, so they'll keep doing it. It is, absolutely, feeding the trolls.
