Why? I realize that money and lawyers can make a big difference in arguable cases, but this DMCA is plainly invalid, it's not possible to interpret it differently without being untruthful.
The demands are to be gone... which it already is, there is nothing to lose in challenging the complaint. Even if concerned about retaliation or further legal action from Casio, all this guy did is essentially glue extra stuff inside a calculator case and publish a video of him doing it on youtube, it's not even particularly interesting from a hacker perspective because nothing about the calculator itself was learned, it's a true duct tape mod.

Are you sure? See GitHub's DMCA counter notice policy[1], specifically, item 3:
> Provide your contact information. Include your email address, name, telephone number, and physical address.
In other words, without paying to retain legal counsel, this guy would have to expose his personal identifiable information (surrendering anonymity) to an unethical, ruthless pack of legal professionals to restore the repo and live with the looming threat of all sorts of perfectly legal harassment.
