Bad reporting - Skype UWP part of Windows 10 Mobile etc.
Sorry, but this article is just bad reporting. All active users of Windows Phone 8.1 devices (i.e. 2014 handsets onwards, roughly) have the Windows 10 Mobile upgrade a screen-tap or two away. And that includes the native Skype UWP (Universal Windows Platform) app. The exact same app as in Windows 10 on all other form factors, including PC.
So let's not have this 'Microsoft abandons Skype on own platform' FUD.
