It's advertising. Are you annoyed at using a free product (Facebook) and having to live with them trying to make a profit through advertising (If so you are in for a painful life as Tv / Radio / Internet.... pretty much everywhere you get this) or are you annoyed at that product in particular? If so why?
I see it as a great tool for certain applications. It will vastly increase the everyday photographers capability at achieving a great shot in everyday setups that often give auto mode some difficulty. Awesome for travel photography under changing conditions. (Assuming it works as advertised and I cant see why not in most cases) It will not replace a pro photographers in many cases as it does not appear to support using off camera lights. (Since it is evaluating light it sees it would appear to be useless with flashes) My bet is, if it works as well as advertised, some big company (Canon / Nikon / Sony) will buy it up and incorporate the algorithms into their automatic modes.
