You know what I love about their arguments?
They first say that it would be a damage to their economy to have a private server of a dead game because it competes with their new game, thus implying that the old game should still have a high population, but at the same time they say that updating a game to make the possibility of unofficial servers available would be expensive because few people would play it.

So what is the truth? Does a killed game have enough people to affect the new one or does it have too few that makes it expensive to update such a "dead" game?
