It is clear that this github repository is to serve no purpose but a rehost, of a copyrighted content(it is open in a sense that it is freely available, but the copyright still belongs to the PG and so on.). While a mirroring is an acceptable contribution to a freely available content, sometimes even encouraged, I've always figured that an accepted approach is to inquire-then-serve, rather than the opposite.
Another problem is that the disclaimer that is supposedly to protect against claims of infringement, proudly calls for the original owners to action, if in case of infringement. Does this mean that this mirror will stay unless the original author spends effort in hunting down these mirrors?
Judging from the email address, I think the guy's heart was at a right place(just because it is an university address) and just wanted to help sharing the good knowledge. Hopefully the share may be moved to more appropriate way.
