MS bought skype just to stop google from buying they. Google made a big for skype and MS swooped in and outbid them. They never had any real plans for skype they just dont want to allow google to gain near monopoly in the consumer VOIP market. Which seems strange for MS to care about since they were not in this sector previously but Ballmer just held such a huge grudge with google and did it out of spite. Really shows what kind of CEO Ballmer was and why MS is so much better off without him
