I can't agree more here. So far Whatsapp and Instagram hasn't been interfered with too much by Facebook, aside from FB completely turning off Instagram API and forcing everyone to upgrade to the IG Graph API way ahead of the deprecation schedule. API support for Instagram DMs is also something that's been long requested for, but ever since FB bought Instagram, there hasn't been any work on the API side. Sometimes I wonder if Instagram would have been better off as its own platform free from the crutches of Facebook. While I'm hoping that it'll stay that way, it's only a matter of time before core Facebook starts to go the way of Myspace and they realize that IG/Whatsapp is the future.
