Actually, it fits very well with the scam model. Rossi has declared a moratorium on further public testing, and has gone to market. IF it's a scam, then the time to go to market is right now before the jig is really up.
What, according to your scam hypotheses, is Rossi's relationship with Defkalion? Who is running the scam and how?
From all I've read of Rossi, he doesn't have the financial resources from his own wealth to operate a scam employing many other people. So unless we start by assuming that everything about Defkalion, Leonardo Corp, Hydrofusion, Ampenergo and so on is internet fakery (with few or no employees or physical locations, etc.) this has grown larger than what Rossi could have managed.
That's why I've been tossing out the mafia in recent suggestions. The idea being that Rossi is cooperating or has been blackmailed into running a scam on someone else's behalf. Someone with substantial resources. But that still doesn't explain the academic side of things, like Dr. George Miley's work here in Illinois or Piantelli and Focardi. If it's a mafia type operation they have an international reach and are able to coerce a number of academics to do their bidding.
The claims for the Ecat are extraordinary, and difficult to sustain based on scientific orthodoxy. But the claims that it is a fraud are also difficult to sustain while incorporating the full range of evidence.
