Well, that is one very cynical view. Of course they might have reasons that benefit users. The fact that they offer an adapter rather dispels this theory. Get good Bluetooth headphones and you won't want to go back. Hint: x.
Not only offer but include it in the box for "free". Apple has been known to pull of some "interesting" things with adapters before like, you need an adapter, buy it. In this case, I was pretty surprised (pleasantly) that they include the adapter.
I had the honor and privilege of meeting Dr. Zewail and attending a private lecture while at university. His daughter was my upper division biochemistry professor and he was kind enough to drop in and give us a lecture while he was visiting. He was a brilliant thinker not just in the world of femto-spectroscopy, but overall. He was approachable and witty. He will be missed as a father, a fellow human and for his contributions to the scientific world.
Maybe. Maybe not:
There have been several studies to date transplanting gut flora from "skinny" rats and mice into "obese" rats and mice resulting in weight loss with the same diet composition. They have also showed the reverse to be true.
Furthermore there seems to be some evidence that sugar-alcohols and artificial sweeteners may be better food for the growth of bacteria that favors an obese phenotype.
(FWIW - I am a doctor (MD) but I am not an endocrinologist/obesity researcher)
