They have been at this for so long that if they are NOT honest they are lousy crooks! I think they are honest and doing their very best for themselves, the Chungs, us shareholders, Tubercin and eventually - mankind. There's WAY MORE here than filthy lucre, eh.
I think Tubercin is going to prove itself (again!) VERY SOON.
