You seem quick to dismiss his review. While the branding of "snake oil" may be an overly strong term, it might not be incorrect: the evidence I've seen thus far (as a user admittedly unfamiliar with the subject) does seem to point to profit off open-source work. But if we were always so quick to give the benefit of the doubt while ridiculing investigations as you did, the thievery would be out of control. I will say that this situation seems like we could take a lesson from Mr. Musk though, and make statements instead of accusations. I'll be interested to see how this turns out.
