Activision notes in the statement that it provided the capital required to start Infinity Ward, and the continued financial and creative support given over the development of the Call of Duty franchise, and that the two execs failed to "honor their obligations to Activision," justifying their dismissal. With the mentions of the company's "enormous patience" and its eventual "disappointment," the full statement (which you can read after the break) sounds oddly parental.
The release concludes with a note that Activision owns the Call of Duty franchise -- though the title Modern Warfare isn't mentioned.
Activision is disappointed that Mr. Zampella and Mr. West have chosen to file a lawsuit, and believes their claims are meritless. Over eight years, Activision shareholders provided these executives with the capital they needed to start Infinity Ward, as well as the financial support, resources and creative independence that helped them flourish and achieve enormous professional success and personal wealth.
In return, Activision legitimately expected them to honor their obligations to Activision, just like any other executives who hold positions of trust in the company. While the company showed enormous patience, it firmly believes that its decision was justified based on their course of conduct and actions. Activision remains committed to the Call of Duty franchise, which it owns, and will continue to produce exciting and innovative games for its millions of fans.
