I imagine the volume of FTC complaints filed against BFL is genuinely enough to have piqued their interest. We know for a fact that the Kansas AG and Postal Officers have a growing file, and Sonny's parole officer is aware of the growing frustrations, allegations of fraud, and are certainly scrutinizing their operation with a microscope that is beginning to zoom in on the subject matter deeper.
The Catch 22 is that should they choose to bring about a Libel and Defamation suit against anyone that has called them to account, is that they will need to, in a court of law, systematically and beyond a reasonable doubt prove slander or defamation by openly discussing their poor performance as a business entity and it all becoming a matter of public record.
Can you imagine the discovery process, where the defendant would be able to effectively open all of Butterfly Labs' books and get a complete window into their operations, effectively gaining all the information they need to disprove and rebut their claims ?
In my opinion, it's just a sad spectacle to take in at this point. The writing is on the wall and all we can really do at this point is sit back and watch the show this Fall.
