Microsoft can teach the special course: how to kill successful products 101.
If I were Satya Nadella I would fire top Skype executives first, cannot believe how a rational company can destroy this brand.
And all those idiots who started converting Lync to "Skype for business" as well. In addition of the nowadays really quirky working Skype, I have bunch of Lync/Skype for business apps installed as well and they are even more horrible and PITA than the Skype.
