I think you only have to look at the indictment to see why they were shut down. Whilst it's an interesting point, and perhaps if the mega empire had attempted to legitimize their business a lot quicker then the indictment would never have been put together, I simply think this falls into the realms of conspiracy theory.
I have posted the full Indictment as a news story, with highlights, for those that are interested in the actual reason for their shut down: http://news.ycombinator.com/item?id=3487808
