| As to your original post,  it's not protected as free speech simply because an ISP is a private company able to do business with whomever it pleases.  Much in the same way as you are afforded no protections under freedom of speech to stand in someone else's house and say whatever you like.
 Amendment I
 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.
 
 In this case,  no goverment body is attempting to interefere with your rights.
