Though much is boilerplate, it's also irrelevant.

Here, we have a DMCA takedown notice that lacks two of the necessary elements: specific identification of the copyrighted work infringed as well as the infringing material.

It doesn't take much to meet these elements, which together would have also allayed public concerns. Barring that, however, it's not a valid notice. As a result, Github has no duty to act as the courts have explicitly affirmed.
