Most people don't care that the iPhone is closed. They don't even know what the difference between open and closed is. And they most certainly don't care.
The iPhone is a phone. It was designed to address problems with phones. The problems it tried to address mostly had to do with the fact that cellphones are almost unusable. For example, I have no idea how to use most of the features on mine, and I'm a geek. It doesn't bother me.
Apple is not interested in hackers. No one is. There are only four of them in the world, but they write in blogs all day, so it seems like there are many more. The main people people who read the blogs are the other three hackers. These four people say the same things to each other for months straight, while companies like Apple and Microsoft rake in billions by serving the other 6.5billion people on the planet.
All the Apple bashing for closing down a piece of hardware that they designed to make money for them misses the point; they don't care about you. Not any more than they have to to get your money, anyway. The way Apple has found to get your money is by limiting options on their products to just what most people want to do. This is how they deliver ease-of-use and stability. Hackers/makers/copyfighters/freetards get angry at the company instead of at themselves for wanting the toys anyway.
But nobody cares what the hackers think. There are only four of them in the whole entire world. They are an insignificant minority.
