If I wrote a song about Obama, yes of course I'd be happy for anyone who wanted to sing it without paying me money. But that's not the same as "be required", I accept.

I can't see that the rather futile gesture of taking down a video clip does anything to protect the rights and welfare of anyone. Doubly futile because it clearly won't work.

I'm inclined to think that it's the inauguration itself that won't a "public event" in the sense that that clip is.
