Actually with Microsoft recently shelving their Response Point IP Phone system, they have not similar competing product, this is just grasping at staws for someone to blame other than the two parties who could not come to an agreement that was beneficial for both. That being Skype and Digium, this contract was more than likely being discussed before the Microsoft deal was even offered.

The Microsoft/Skype deal is nowhere near completion, and Microsoft currently has no say in how Skype runs their business. Also the negotiations on this software were most likely ongoing long before the Microsoft/Skype merger was announced, and most likely a business decisions based on profit margins and longevity. I can't help but wonder why people are so quick to blame Microsoft for issues that they could not possible be responsible for.
