$FB: Revenue was $3.7B in 2011, and over $40 BILLION in 2017. They had 1 Billion users then and now have 2 Billion users. The question is: revenues went up 11X while users went up 2X. Are we sure they just sell ad space? .. I am guessing they sell data ... your data (sensitive metadata and information) and family's history as well! #DeleteFB #SteemIt
