That is the billion dollar question. What is their real motivation? All clinical biotechs get shorted and manipulated, but this one is a virtual vendetta.
Professionals can be as foolish as all mortals at times but even as temperamentally flawed and ethically challenged a professional investor and advisor as Jim Cramer would never have survived such petulance in a most precarious career if he allowed himself to be ruled by such an emotion against an amorphous object through various lifetimes.
Rationally one should look for the underlying reasons such as the partially irrational fear of the deadly Listeria bacteria. Prof. Paterson whiled away years in her UPenn lab while a glorious cancer vaccine boom soared and then went bust.
One of the first to take her truthful message to heart was the infringer who created ADRO. A second was the courageous tyro CEO who had spectacular results with a cheap Phase I but funded by a vulture more deadly than the bankers that crashed economies around the planet.
But why does it continue on and on.
In my opinion a chief culprit is the counterproductive attempt to deny the fact of what the basic foundation actually is. The ugly duckling is actually the long sought after efficacious cancer vaccine.
Look closely and you will see that the single entity that proved it clearly understood that Yvonne had created a glorious swan instead of another duck was GOG. I would say they were always the ones giving Advaxis wings and it was a rare bird like Amgen that noticed.
But continue on with the vendetta talk if you wish. It pleases many who dare not look up.
