Let me be very clear. The First Amendment to the US Constitution says: Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances. The court has ruled that this also means that humans can use their property in the furtherance of speech. Such property can be a printing press, a computer connected to the internet, a corporation, a ship, a billboard or other such things. Some of those pieces of property are legal persons (corporations, ships), others are not. The personhood of the piece of property is irrelevant.
