Therefore disseminating information about where you can download something is speech.
I agree that disseminating information is protected speech. I do not agree that disseminating the copy written property of someone else is protected speech.
The moment you start deciding that one thing is speech and another isn't, regardless of your personal views on the merits of that speech, you begin running headlong towards despotism.
Actually you begin running headlong toward a civil society. Hate speech, incite to riot, libel, slander, etc are not protected speech. These types of speech have been found to be detrimental to civil society and have been made illegal in most places. Just because something is auditory in nature does not make it protected speech.
