I make my living from YouTube, and I am going to explain what’s behind that link.
When a creator receives a Content ID claim, that’s the beginning of a process, not the end. Content ID claims can be disputed, and during the dispute, all revenue from the video is held in escrow, eventually going to whomever prevails in the dispute.
The first level of the dispute process is essentially the uploader asking the claimant to reconsider, with the option to provide a brief explanation of why the uploader believes the claim is invalid. There’s even a radio button to select if you believe the material is in the public domain.
If the initial dispute is rejected, that’s not the end of the story. The uploader can press the dispute further. Doing so forces the claimant to either abandon their claim, or ‘upgrade’ it to a formal DMCA takedown.
If a takedown is issued and the uploader believes their work is not infringing, they can respond with a counter-notification, which forces the claimant to either (a) sue the uploader within ten days, or (b) lose the dispute. In the latter case, the video goes back up and any escrow revenue - along with all future revenue - goes to the uploader instead of the copyright claimant.
Behind the “Select Action” link is the option to initiate the dispute process I just described. Which the uploader almost-certainly already did.
Also behind that link, IIRC, is the option to contact the claimant via email. That can be an equally-effective path toward resolution, as it provides the opportunity for a more casual, professional dialog, outside of YouTube’s formal process. In fact, on one occasion I developed a positive and ongoing business relationship with another media outlet after being contacted by them regarding a claim that I had made in error.
When Content ID first rolled out in 2007, it could be easily abused. And it was. But that was almost 17 years ago, and the way it works today is - dare I say - pretty good. Like any enormous system it has its problems, but on the whole it’s pretty fair.
Edit:
There is one other option behind the “Select Action” link. It’s irrelevant in this case, but I might as well include it here for completeness.
If the claim involves only a portion of the video, or the audio in the video, the uploader is given options to (1) excise the claimed section of their video, (2) silence the audio in the claimed section, or (3) replace the claimed audio with music from YouTube’s (huge) library of free music.
If the uploader chooses any one of those options, it immediately resolves the claim in their favor, since the claimed material is no longer present in their upload.
