Guess what he's actually saying is that if you want to created "walled gardens" and locking-in users HTML5 is not the way. So if you want to collect fees from publishers, don't own the browser or the OS (and are not the content creator) - use a closed app. From the viewpoint of FB this might be (a short-sighted) way forward. It's not in the interest of the publishers and content providers - but again that seemingly doesn't bother FB.
