After being acquired by Microsoft, their product strategy for Skype was unclear. It was still offered as a standalone application, and at one point it got Facebook login integration and eventually Microsoft account integration. In 2013, they shut down WLM [1] and told everyone to use Skype.

Meanwhile on Windows Phone, it was discontinued on WP7 [2], while WP8 had native 'iMessage'-equivalent apps backended by Skype, but also a downloadable Skype app. If you installed both, you got double notifications. Was it supposed to be the platform-native messenger? On the phone, the answer was 'yes', but on the desktop it was 'no', or 'not yet'.

Desktop Windows 8 eventually also got a Metro app, but then it was killed [3]. Now they're about to release another one [4].

I was wondering what's wrong with WhatsApp. Sure it lacks video calling, but it's arguably my number 2 messaging app. Rock steady, deliver/read receipts, fast..

The text messaging sucks in multiple ways.

Not on Linux.
