This falls under total Microsoft fail. After a year of telling us that they had moved to Skype internally and then failing to deliver Skype for clients! Microsoft has already admitted that Lync was a failure and that they don't use it themselves anymore because it is so bad. Now, after making a big deal that Skype was the future, they've decided to bail on Skype.
If Microsoft isn't eating their own dog food on this one, I doubt we should either.
