If you take the reasonable assumption that their job is to sell ships then I think a lot of the picture falls into place. They'll devote their limited time to working on the new ships they're being instructed to sell, not fixing the old ships because if the old ships are just as good as the new ships you'll sell less new ships. Player churn is good because if an old player drops out of the game but a new player comes in they'll sell more ships to the new player buying up back-catalogue than to an old player who only needs a few of the new ships. If the competitive metagame becomes enough of an issue that it starts to affect attendance, and thus sales through implication, then they may need to make changes but otherwise their focus will be on making new ships to sell over errata for existing product.
