Worth noting that those other companies owed far more also have significantly more resources and assets then 2600. Adjusted for size, it is a terrible blow for them.
On the other hand, if 2600, not to mention the other small fry publishers, can survive the blow, they can essentially free ride on the legal efforts of the big fish in their creditor class. There's enough money at stake that Time Warner et. al. will expend plenty of effort, if they perceive there will be a sufficient payoff ("can't get blood out of a stone", sometimes the best you can do is force a Chapter 7 liquidation and get a few pennies on the dollar for your efforts).
