I don't think that's precisely right either. If I've understood the article correctly, she has three options here: sign up to the new agreement and continue receiving revenue from third party uploads that ContentID matches to her content, stop receiving third-party revenue and leave all third party videos up, or stop receiving the revenue and take all third party videos down. I'm not sure this would even stop her from getting ad revenue from videos that she uploads herself (the article doesn't discuss this). ContentID accounts are about getting revenue from things other people upload that include your content.
