Who cares is it’s the “central part of their business” or not? That’s a stupid straw man.
He wasn’t “just an investor.” He controlled the majority of the shares in the company. In other words, he controlled the company. He was the owner.
You haven’t thought this through, it’s obvious.
You are blowing this way out proportion. You portray MR as a concentration camp worker tossing human bodies into an incinerator like something out of the Holocaust.
He invested in a company which develops systems to help dispose of medical waste that millions have others have invested in as well which sell billions of dollars worth of products and waste removal systems. The fact that a tiny number of these products and systems wound up in some abortion clinics does not make MR or any other Stericycle shareholders or investors guilty of practicing abortion IMHO.
