That's an entirely different discussion on the increasing privatization of public space.
We've long established that companies don't have a right to "play by their [own] rules." For example, in the US a mall cannot discriminate on basis of race, and it must follow ADA, OSHA, and other requirements.
Remember, companies exist only because of government regulation. They exist because otherwise individual people (the owners) would be responsible for mishaps and debts, and that's too much risk for most people. Since we set the law, companies must abide by our rules.
And that leads to an entirely different discussion on the influence of companies on lawmaking.
