Why is being the only one selling Apps on a platform not having a monopoly? I never said, anything about selling Apple products. I said that Apple is the only one selling Apps on the iPhone. If you want to sell an App for iPhone you
have to accept the 30% cut.
The definition of a monopoly:
"exclusive control of a commodity or service in a particular market, or a control that makes possible the manipulation of prices."
This is exactly what apple does!
"I can buy magazines or newspapers from hundreds of sources."
I never said that newsstands have a monopoly. I said they "have something
like a monopoly" in a particular place, because people usually buy newspapers when they have nothing to do, and don't plan where to buy them. When you are at the airport you usually accept the high prices, because there is no alternative. Or if you not live in the center of a city where you have multiple newsstands. With the internet you can buy where you want when you want. So the competition is much bigger, resulting at the moment in most of the newssources being free.
"I can buy computers, phone or tablets from dozens of sources. To say that Apple has a Monopoly of apple products is sophistry and shows you have no understanding of what a monopoly is."
Where did I said anything about computers, phone or tablets? I never spoke about Apple products. Do you even rode what I wrote?
