One small nitpick or a large one depending on your position, but the author seems to subscribe to the concept that corporations are people. Never the less, even if one subscribes to it, I as a individual have a right to boycott anyone I want to, if I don't like a person, I can ask them to leave my property and I can not engage in commerce with them. If they are adamant about their right to speech then they can stick to their guns. There is nothing about the right to free speech that protects revenue for supporting a position that is in direct contrast to others rights. I find the conclusion draw in that sentence to be dubious.
