I was addressing this nonsense specifically:

"Why did Rauber think that the technology was further along than it was?...Could it be that he was not given the complete truth? Just as shareholders have not?"

No, he did his own DD, and stated in front of a room of hundreds of people, including you, that he didn't leave a Fortune 500 company for a maybe and guarrantees he will not fail.  I find it laughable than message board posters think they have it all figured out and it was Rauber that was misled and should have listened to posters.  Rauber knew whatever challenges remained and decided based on his own experience and DD and engineers etc. etc. that they were minor.  Like an Oxygen sensor (as an example).  Before you have the Oxygen sensor melting problem solved, once can be 100% confident that a problem like that, as an example, will be solved and has little to do with the tech itself.
