I don't see how Github could've handled this differently without jeopardising their safe harbour status...
The issue is with the copyright system, not with who hosts the code.
Unless you host it in a country that doesn't have such copyright laws and has no relevant treaties with the USA or other countries that do, with a company that also doesn't, on a domain name that also isn't registered with a company or TLD that does.
