When Microsoft bought Skype it was to deal with a couple of issues. One of the big ones was to remove a competitor in the communications market and the other was to make sure they were not going to get sued for the direction their own communications services were taking. Microsoft had been floundering in the consumer market despite the multiple changes they tried to make to their messenger product. While their enterprise messaging software was complicated and expensive to maintain and to properly integrate with other messaging services. To combat this Microsoft was already looking to make their messaging services much more like Skype than they were.
