There are no heroes, here. No anti-heroes, either. This is not an homage to Istvaan Shogatsu, there was neither patience nor art involved. Goonswarm should not be accepting this windfall as if it is their due and Band of Brothers is solely responsible for their fate.
The information I have gleaned from the various infosources collates as follows:
Someone with director-level access to BoB's holding corp is disgruntled, and in a fit of pique handed the keys over to Goons.
The perpetrator is BoB's creation: they made themselves vulnerable by not being more cautious in whom they placed their trust, and through internal issues, made him upset enough to betray them.
The behaviour as witnessed in Goonswarm's press-release audio recording was juvenile in the extreme. Others have mentioned this as well: rarely have I heard such overt hatred expressed so shamelessly.
Band of Brothers will rebuild. They will clean the house which their long-running frat-party has so liberally trashed. They may even emerge the stronger for this; who can say? Goons will do everything within their powers to utterly fuck up everything of BoB's which has been left vulnerable in the mean-time.
And we who prowl the narrow boundary between Concord control and capsuleer space, will reap the benefits by continuing to shoot and ransom their pilots. C'est Eve.
