Reading between the lines, the story basically suggests that Google changed since Page took over. Okay, new management, new direction, new profits. How many times does new management cause people to quit? A lot. An article like this may indicate cracks but last time I checked their market share didn't dwindle, they own 95%+ of mobile search (which is the future) and this is one of the very very few stories out there. Show me more articles then I might be willing to put some credence into this. It doesn't make me feel any better about things regarding the future. Let's not forget that ads on Facebook have been the furthest thing from a success. How are FB shares doing? I think the writer is guessing about the perceived threat that the executives feel about FB.
