The only way to stop that is to violate corporate rights. Are you willing to do that? Are you willing to make it a felony for a corporation to lobby Congress? I am. I would love to give people from the RIAA life in prison for their lobbying.
No, I am not willing to do that.
They have as much right to call their congressman and complain as you and I do.
Just because you become a business owner or executive doesn't mean you lose your first amendment right to free speech.
