They aren't innovative, the market is saturated, new users in developing countries are not worth as much as those from "first world countries".
As the users in first world countries are getting more and more aware of all the privacy issues, how FB fails to keep their platforms clean (either from spam or fake news) and other companies starting to like the taste of being valued as "privacy-friendly", the business model of FB is starting to crumble.
