Go here to read the whole thing, which includes some biz theory discussions of supplier power, adding value, commoditization of businesses, and related topics, but the money shot is the last line:

Why do I love Apple? They intend to make money because of my desires, not despite them.

Contrast ATT and Apple. AT&T wants to tie you to their network, and wants to make money from you at every turn. They’ll gladly fuck you over for an extra $30 a month, secure in the knowledge that you’re in a contract. Apple, on the other hand, damn near has a cult of motivated users who are actual FANS of the brand. This is why.

One of these options is a good business model. Guess which one.
