Big brother Microsoft listens in to your Skype IMs
Summary: Yes, Microsoft is recording, at the least, your Skype instant messages, and they have the potential to record your voice calls as well.
According to a Microsoft Skype spokesperson, “As was true before the Microsoft acquisition, Skype co-operates with law enforcement agencies as is legally required and technically feasible.”
Therefore, any person or business who is concerned with their communication privacy should stop using Skype and look for an alternative.

Skype jumps the shark: Seven alternative VoIP services
Summary: Microsoft is adding advertising to its voice over IP (VoIP) service Skype. Fortunately, there are lots of alternatives that don't stick an ad in your face while you're talking.
Hundreds of millions of people use Skype for its free voice over IP (VoIP) services every day. Indeed, Skype claims that in March 2012, 35-million people were all talking at the same time on the service. But, how many of them are going to stick with it when Microsoft, Skype's owner, sticks ads in your face?
So, you should think of Conversation Ads as a way for Skype to generate fun interactivity between your circle of friends and family and the brands you care about." Oh yeah, I always like having an ad pop-up when I'm talking to a friend or co-worker.
These ads, which will use your location, age and sex to better target you, will appear on Skype for Windows if you don't have any Skype Credit or a Skype subscriptions while you're making 1:1 Skype-to-Skype audio calls.
