Why is this still complex for people after 15+ years? Google's business is selling ads to an audience made captive by "free" email and search (I include Maps here) paid for by the privacy of that audience. The rest of what they do is wanking because they have more money than they know what to do with, the incremental info they get from most of these projects is nil. Google "strategy" these days is to make an inferior copy of other people's ideas, try to leverage their captive audience by strong-arming them and then failing anyway. People have been ripping on Apple lately, but Google is in exactly the same "no-innovation" spiral. They are ripe for disruption, it is only a matter of time.
