This is an insightful comment. It is easy to forget not just how different Facebook of 2017 is from 2007 but the cycles they've gone through. Facebook measures and adapts to user engagement. When something spurs a loss of engagement eventually it disappears. In the social space, other tech companies struggle just getting a few new things shipped and then bail when they don't look like they are working out. It is in Facebook's best interest to see Snapchat fail. The next big thing that comes around, it will be a lot easier for Facebook to buy early on. On another note, if Instagram, Messenger, Whatsapp, and Facebook all start looking like the same app, it gives Facebook a particularly powerful platform. Everything could end up being rolled up in to a single app in the future -- or a new device.
