Facebook's interest in bots has nothing to do with enabling the delivery of amusing gifs and everything to do with becoming the de facto service to prove who you are on the internet. If that service is in the first-world Western internet then who you are is proved by an OAuth secret tied to your Facebook profile. If that service is in the developing world then it's going to have to work using a mobile chat app and a textual interface, and be on a network that user's are happy to use because the data comes free from Internet.org ... eg a bot on Facebook chat.
All of Facebook's chatter about bots is about getting people to register on Facebook.
