Microsoft is doing a service to all of us by destroying Skype. Nobody should use it anyway from the moment MS has bought it with sole purpose of handing data over to NSA&Friends.
Secondly webrtc requires you to coordinate, it's not like I can just call someone. Just as well we could use TeamSpeak or Ventrilo or any of the old solutions.
I much prefer Hangouts over Skype though, plus it performs very well on Ubuntu, unlike Skype.
