But who actually wants it? Who wants a fundamental part of their daily work suddenly manipulated by somebody else at a whim?
What if Ford decided it would force-push add a cool "Star Wars" tie in to its cars (no pun intended on "force push")? That's a mission-critical part of my life, I drive my kids in it. Don't mess with my car over-the-air without telling me, I don't care if it's all fun and games to you, to me it's my life.
Same for my browser. It's not a toy I use for fun. It's how I see my medical records, pay bills, transport extremely sensitive and confidential information... I don't want anyone to suddenly push "cool fun easter eggs" to it, under any circumstance.
