Corporations have been been judged by the Supreme Court to have a right to free speech, just as does the individual. Any business who has the desire to risk their business over political issues has that right, on either side of the current debate.
These large entities spend millions of dollars deciding what "policies" will sell more Lattes or burgers. That is part of the magic of marketing. They know that they will please some of their customers or potential customers and repel others. They make decisions based on the bottom line, not some moral philosophy. While Corporations have the right of expression, they lack human qualities of introspection and the sense of right and wrong. They only worship the bottom line.
