No, that's not quite what the opinions in the case stated. Justice Alito went so far as to state in the court's official opinion that...
"Any suggestion that for-profit corporations are incapable of exercising religion because their purpose is simply to make money flies in the face of modern corporate law," Alito wrote, adding that by requiring religious corporations to cover contraception, "the HHS mandate demands that they engage in conduct that seriously violates their religious beliefs."
How does that not apply to any and all corporations? Who's to say that a rich fundamentalist Christian individual or family couldn't purchase enough shares in a public company and gain sufficient ownership so that they could place members of their choice on the BOD where they could then influence company policy under the belief that the Supreme Court has just protected them doing just that?
