Well if it's directly related to poor sales of FSX then I'm not surprised. FS2004 was a highly respected version of MSFS that still works well on almost any hardware launched within the last 2 years. Development of third party add-ons was relatively simple and many great developers invested heavily in this area. FSX has turned the sim into an eye candy laden piece of drama that lacks flying realism and demands expensive hardware. The flight models just get worse with every new version. The average user is satisfied with a piss poor 12fps but experienced users will be looking for twice that. And there is the problem. Recently, MS have been targetting the sim at the wrong crowed, wooing them with graphics and eye candy. All the while casting aside the serious FS user who demands accuracy and realism with respect to flight modelling and atmosphere modelling and efficiency (efficient software that is not resource hungry).
