This statement as an absolute is dead wrong economically. If you put a qualifier on it perhaps stating that this is a bad practice if you are refusing profitable business, then perhaps there is a point. One of the major learning points in business is when to get out. Leaving dying fruit on the vine is sometimes much more profitable than picking it and trying to sell it (my Grandpa would be proud of me using something he used to say here, lol). I am relatively (and by relatively I mean 100%) certain that this decision was made with the goal of cutting economic and physical waste and to improve the overall economic performance of XBL. That, in the end, will benefit you more than keeping dying systems or games alive.
