I can't answer 1,2 and 4. Partly because I'd have to do some analysis and partly because I'm not sure I (we?) have enough info to determine the answers. Can you provide an example of something specific to get me thinking?

I may not be interpreting your question correctly, but no, not 100%.  For one, PoW ended much sooner. Some deliverables have been shaky but there is no way that I can jump to the conclusion that they intentionally misled anyone. Problems with rollout can easily be blamed on shit going wrong and people leaving. Executing big projects is hard even if you have a perfect strategy.

Are they open to discussion? Yes, I think they are to an extent or at least were at one time. If you are being fair, you have to admit that not all of the contents of this thread qualify as "discussion." I think people have their limits but at the same time I'm not delusional enough to think they executed communication perfectly.
