Hogwash, my asking of the question only suggests there is no clear answer. The hypothesis that there is serious unresolved issues is your creation. There is no evidence that there are serious unresolved issues and there is no commercialization so there is no clear evidence that there are not serious unresolved issues.
Furthermore, funding is not a concern at all for anyone looking objectively, IMO. The company has little debt and lots of shares that can place to raise funds to stay alive. Again, that is more of a spin position by you than a realistic or real concern.
