Nobody is saying that everyone should host websites on your phone. The author is saying you should be able to, if you so choose. Android and iOS put restrictions on what applications on a phone are able to do, often for arbitrary reasons.
You can't hack a web server in your closet to run on port 80 without jailbreaking your phone/unlocking the bootloader and rooting your phone, and I can't really think of a reason why that should be. It's not as it Android and iOS come with important http(s) servers out of the box, why shouldn't port 80/443 be available to apps?
