github.com/knockout/knockout was one of the repos listed, and here is the letter they sent (which seems to be a reasonable template):

It has recently come to my attention that your firm has filed a DMCA notice to Google identifying copyright infringement for works to which I am personally associated. I apologize if this email is not directed to the correct address, but it was the only address apparent to contact your company and I would be grateful if you could forward this message appropriately or direct me accordingly.
The notice that has come to my attention includes the details from the web-site as follows:
This site identifies Takedown Piracy LLC as an agent of Wicked Pictures sending a DMCA notice to Google. The notice apparently references the following works, which works appear to have since been removed from the results of searches via the Google search engine:
These works are entirely software and are in no way associated with Wicked Pictures, nor do they contain any adult material whatsoever (which I understand to be the preponderance of copyright held by Wicked Pictures).
Through the above-referenced DMCA notice your firm has stated that I have committed or endorsed copyright infringement, as well as associated me with republishing unlicensed works of the adult industry.
[As a software developer], I am sure you can appreciate that the above implication and association could cause serious harm to my reputation.
I trust you will not mind issuing an appropriate revocation of appropriate portions of the DMCA notices to Google and any other recipient that may have received a notice referencing the above content, as well as similarly revoking and white-listing from any future notices any work referred to with a URL containing the following:
âAgain, these repositories contain entirely software and are clearly not the intended target of your operationâ, which you can readily confirm by navigating to them in a web browser.
âMany thanks for your co-operation on this matter, and I would be grateful for your âconfirmation that the DMCA notices have been appropriately revoked. If by February 7th, 2015 it is apparent that the DMCA notices have not been revoked, I will be obliged to pursue appropriate legal action, and will hold your firm responsible for all associated legal costs.
