They deduced that regardless of the outcome of the acquisition, the software giant would not have the volume of users for them to spend their time and money.

In an interview, Development head and co-creator Tommy Palm of King.com said, "With or without Nokia, Microsoft needs to demonstrate that they can capture a material segment of the mobile market. We will wait and see." King.com developed Candy Crush, the most addictive game in the world.

Bloomberg's interviews with over a dozen of mobile developers confirmed the hesitation of many app makers to partner up with Microsoft. Microsoft only had a small share in the smartphone market share, and it was evident, for example. with its number of apps for the Windows Phone.
