"Microsoft has full control over it and can decide at any moment to... well, for example, shut it down." Not if people decide to write their own server software for it. i.e. Something that you most certainly can't do easily with Skype as it's leaps and bounds more complicated to reverse-engineer. "Not saying skype is better, just glad to see crappy proprietary tech die out." What? Let me rephrase how I re-read your sentence: "Not saying skype is better, just glad to see crappy proprietary tech get replaced by even less open and more difficult to reverse-engineer tech." Why would you be glad about that? You're contradicting your own viewpoint about how bad "proprietary tech" is by advocating it's replacement by an even more "proprietary tech"
