Marc Whitten leaving the company now strikes a potentially huge blow to the future of this service. Whitten has a lot of experience in the industry, as he worked at Microsoft from January 1997 to March 2014. He helped with the inception of the Xbox brand, including in its most successful Xbox 360 years. Clearly, the man has plenty of knowledge of how this industry works, meaning Luna could be in serious trouble if he is leaving the project so quickly.
