> Assuming you're referring only to the §1201 'anticircumvention' portion of the claim (the main focus of the GitHub post), whether this portion is _also_ subject to §512 rules is a little more ambiguous. §1201 defines a trafficking violation separate from copyright infringement itself, but some court rulings have established a requirement that §1201 violations establish a 'nexus' to copyright infringement in order to be valid. If this is true, the §512 safe harbor protections could indirectly cover §1201 claims as well.

I don't think that even if the first is true, the second is true: even the courts that hold the "nexus" position don't, AFAIK, hold that Sec. 1201 liability requires that the trafficker be already liable for contributory infringement, only that there be a connection of the trafficked circumvention measure to infringement.

OTOH, if its not covered by the safe harbor provision, that doesn't mean notice of the violation is irrelevant; knowledge is explicitly relevant to one route to liability under Sec. 1201, and arguably necessary for any of the others; notice potentially take the host from being an exploited bystander to a liable trafficker, provided that they do not take action to end the trafficking on their platform.
