"to the benefit of nobody"

Apple is benefitting. Apple is right to look out for their own interests - they should behave in ways that are good for them, long-term. If you think Apple's actions aren't good for it, fine, but remember that you don't have all the information they do.

If customers don't like Apple's policies, they are free to competitor's product. If developers don't like Apple's policies, they are free to develop for another platform.

I love Apple's products, and I'm going to continue using and buying them.
