It was Microsofts fault. I had a Windows Phone just to play with it (besides an iPhone), Nokia Lumia. Just when Windows Phone 7 was getting some traction, Microsoft axed it and rebooted the ecosystem. None of the popular phones that ran Windows Phone 7 got the Windows Phone 8 update. To make it worse, Windows Phone 8 apps were not compatible with Windows Phone 7.

So Microsoft basically said: "as a thanks for being an early adopter, you know have to buy a completely new phone again". For reference, Windows Phone 7 was initially released in October 2010 and Windows Phone 8 in October 2012. After that many (technically-inclined) early adopters left.

Microsoft destroyed Windows Phone.
