No thank you..
Just like "free messaging" is a way to get people off SMS that is slightly harder to intercept, so is Skype an effort to make it much easier to tap into global communication.
Skype started with a peer to peer model that *worked*, but P2P is a swine to intercept so when MS got its UI-destroying paws on it it eventually moved from P2P + super nodes to "everyone talks to a couple of data centres" which is what it is today. You have no control over what is retained, you have no view of who is listening in. and if you believe Microsoft's posturing about privacy to be in your interest you need your head examined (or start checking what the company's DNA is by checking what it has been up to for the last 3 decades or so).
No thanks. There is a wide open market for something new (not too impressed with WebRTC either, but it has potential).
