If you buy that book, do you also buy the rights to the ideas, the format, the layout, the pictures, the typeface, etc. Can you then reset the pages, print up a new edition and sell as many copies as you want to the general public? The book analogous to the computer, the OS is analogous to the words and pictures on the pages.
You can sell the book, burn it, lend it, give it away, tear it up, cherish it, draw in crayon in the margins, but you don't own the ideas or the rights to do what you want with impunity with what's in that book or claim the words in it as your own. Nor can you make a copy of it to give to your friends.
Essentially, although you do OWN the book, it is a license to read what the publisher has placed in the generic holder...

If you have a phone -- and a phone line, a phone number, which you pay the telco for each month -- does that entitle you to connect a "blue box" to use it to gain access to "free" long distance calls without paying the telco's tolls and fees?
Just curious. Just trying to get the lay of the land.
Selling a tool that lets a person install his own legally purchased copy (not purchased license, purchased copy) of OS X is not the equivalent of pirating OS X DVDs and reselling them. But the doctrine of First Sale says that once Apple sells me a copy, Apple loses control of that copy. They have no power to tell me what I can and cannot do with that copy, as a publisher can't tell me what to do with the book. The expanse and limits of their powers are already defined -- in copyright law.
Developers are free to give away their own rights, such as open source freely allows copying. That is the true license, as a license is an allowance to do something you would otherwise not be allowed to do under law (in this case under copyright law, copy and redistribute).
The big question is, what gives them the power to grab more rights than copyright law gives them to their software in the first place?
