-- "In 2008, when the company was owned by eBay instead of Microsoft , a Skype spokeswoman told CNET : "We have not received any subpoenas or court orders asking us to perform a live interception or wiretap of Skype-to-Skype communications. In any event, because of Skype's peer-to-peer architecture and encryption techniques, Skype would not be able to comply with such a request."
-- "After buying Skype, Microsoft dramatically overhauled its architecture, replacing peer-to-peer "super nodes" with thousands of servers run by Microsoft -- a more centralized approach that may have made it easier for government eavesdroppers. Around the same time, Microsoft would no longer stand by Skype's earlier claim to be wiretap-unfriendly."
