This is really endemic of the difficulty virtual worlds are going to have gaining recognition. To an outsider, its a case of "so what," but to the virtual world people inhabit and dedicate themselves to, its as if the colonial English empire suffered a Babylonian confusion of language and was no longer able to talk or work together. All powers great and small are rushing to fill the power vaccuum left in their wake, to claim the profitable and rich bounds of space this alliance once defended.
The case is more complex than that; EVE, unlike every other program out there, is a contested world with rich rewards for those holding space. By disbanding the alliance, these people no longer hold space. The space and its wealth of resources are up for grabs and there are suddenly dozens of major parties joining the frey to claim it. Alliances who ship off to the freshly claimable Delve seeking riches fortune and fame are subject to attacks at their homelands.
EVE had been at a status quo for nearly 3 years: there was an established Northern Coallition, the southern RedSwarm Faction, and BoB. Each group has made attacks, but none have succeeded in storming the others home or ruining the other. Disbanding BoB has destabilized a perfect balance, and instilled a sense of adventure in a lot of people who'd found the universe growing boring and stale.
In closing, I can only lament how unfortunate it is that this titanic event will go unnoticed and unappreciated for so long. If this were an article about someone beating the newest boss in WoW I'd throw up my hands in disgust, but theres something fundamentally different about the limited and player driven world of EVE: the events in it are shared between all the players of EVE, and this great confusion has thrown a very interesting twist into what had become a rather stalemated game. I hope more games follow EVEs pattern of making rich and authentic universes where actions have consequences and great powers and alliances rise and fall, but I think it will be a long long time before these worlds come to domainate & the populous feels their tremors as readily as they feel the throws of power in the real world.
