Great point. Very often people when people don't understand a business, or dislike it, it seems that they reduce it to its superficial components. Eg "Uber is just private taxis", "Amazon is just an online bookseller", "Twitter is just a microblogging service".

There's usually something more to it than meets the eye, if you're willing to look.
