I'm not ignoring it, I'm saying that "if someone wants to" then they will find away, even if they have to create that way (hence the reference to the various codes and industries that popped up to circumvent those codes). In this case, the willing audience flipping to CNN or Fox news or anyone who carried the broadcast would allow them access to the speech.
Similarly, the unwilling audience could have flipped the channel to anything else had those broadcast networks not turned off the speech. But your argument seems to be is that private corporations who broadcast these channels don't have the right to choose to be a willing/unwilling audience, to which I would disagree.
