Dew, Man isn't that the truth. If Bianco had only dropped Xyotax completely and concentrated on Pixantrone, but nooo... They always choose to whip the dead horse, and run the company into the ground.
A similar phenomenon occurs in research labs. Dependent on grants, they'll do whatever it takes to continue getting funded. The amyloid vrs tau wars were an example, where for years labs could only get funding if they stayed within the amyloid orthodoxy.
