It seems to me that facebook has all their eggs in one basket whereas google is extremely diverse (even though many of googles' ventures inevitability feed back into search). I think facebook haven't used their huge cash reserves wisely which is why faltering in a single area (aka. advertising) puts them in a very precarious position. What has google done (just off the top of my head)? android, gmail, google maps, search, self-driving cars, glass, hardware (I know the nexus/q are manu. by asus but google do have their name on it) What has facebook done? facebook.com, facebook app for mobile? thrift?
