Everyone buys companies. This is nothing new. If the threshold for Facebook buying companies becomes too low, the startup sphere will be flooded (which to some extent has already happened) and Facebook will stop buying them all (which to a degree is true already). Eventually there will be enough that goes under their radar or enough companies to say no to their offer (e.g. Snapchat) that stuff will get through the buyout-barrier. Everything old is new again, yawn.
