Indeed... Same (possible) holds for PayPal. I really don't understand why companies like Snapchat and PayPal don't do the reverse - add Facebook-feature to their product! Surely Snapchat would be more useable if it had profiles, friends, etc. (i.e. if it became Facebook-lite, in other words, Instagram clone). Sure, (some) users will revolt, but you don't need to force it down their throat... make it opt-in, or privacy-preserving, or something, and make sure that it's genuinely useful!
