WHY DO CRITICS CHARGE THE NEW YORK BLOOD CENTER HAS BLOOD ON ITS HANDS?

This is a story I just can’t understand. How can the New York Blood center think it is okay to just drop these chimps off on an island, with no natural food or water, abandoning them. The same chimps they used in experimentation for 30 years. I just don’t understand the thinking. The inhumane behavior. And the unethical behavior and judgment.
