I can't believe it either. And it doesn't stop there. Car companies start putting Android in their cars and really think customer will like it. I wouldn't even buy an Oracle DB but use Postgres, even if this seems a bit too paraniod. Everything Open Source and no public services / hosting is the only answer.
Psst, Android is open source. So if you want everything open source, Android-powered car infotainment should make you very happy.
Actually, Android is not entirely open source. Some key components are closed source, that's why project like cyanogenmod exist.
