Stupid or not it is consistent NWBO's corporate culture to keep shareholders in the dark as much as those laws and regulations which are actually enforceable allow.
Even the use of Cognate and now Advent is a way where core activities are outsourced to a privately held company that management controls allowing them to have their cake and eat it too as far as being a public company and yet leaving a lot hidden because it is being done by a private firm.
Even back when NWBO was actively courting shareholders (the Red Chip Report and Fox Business era) they were always slippery in their use of language and as time has passed they have gotten to such an extreme that even very broad and generous expressions like 'coming months' cannot be relied upon at all.
If NWBO was a privately held company, this would be fine. If clincaltrials.gov was not a government website that patients, doctors and yes investors rely upon for accurate information then this would be fine.
While this is not fine, it will continue to go on and with no end in sight. At this point, it is doubtful that even stellar TLD that gets an article referenced on the front page of the best journal is going to magically fix this company's behavior. It is just too deeply ingrained.
