I'd argue that companies don't care about anything as they are not sentient. The culture and morals of a company is an aggregate of the morals of the people that operate and make up these companies, so this "companies care for shareholders" being a free ticket to doing immoral things does not get anyone off the hook (morally speaking). Of course life is complex, things aren't black and white, etc. etc. but I still believe business can be successful without being evil (whether it was originally intended as marketing message or not)
