What he doesn't understand is that while facebook is very popular today it could easily be in the same boat as myspace tomorrow.
I didn't buy my iPhone to hang off facebook 24/7, that's just an app I use once in a while. I realize they want to push it as "the main reason anyone exists at all" but it's just a website.
1. He's the CEO and founder of Facebook. Why would he share that line of thinking - that it might be in the same boat as myspace tomorrow.
2. You don't need to worry. Home isn't coming to iOS as anything other than perhaps an app. You don't need to download it. And no one is forcing you to buy a phone that has Facebook Home installed on it.
Problem solved
