From Apple point of view those examples aren't interesting from business point of view.

If GNU/Linux wasn't free as beer and people had to pay for it, all those use cases would never have happened.

Hence why it is almost impossible to sell software to GNU/Linux users, and one has to get by writing books, selling consulting services or support.

Free beer means you get the beer for free, it doesn't mean you get the recipe.
