For two reasons, I agree with the article's premise that YouTube is screwing things up for its users.
First, my video actually lost all audio when I tried to use the AudioSwap tool yesterday to reinstate my video after YouTube blocked it from public view; the video (and sound) still previously viewable in the edit pane of my YouTube account. I've just tried again with another AudioSwap song from their library--maybe now it will work and add a song.
Second, my video was simply a parody of the music video set to a real song, which there are likely millions of on youtube.
