the owner of the repo that has been taken down can file a counterclaim (that may not be the word, I am not a lawyer) which the original DMCA-thrower must respond to within 10 days. if they do not respond in 10 days, or the response is insufficient in some way, the repo goes back up.
this whole time there is nothing GitHub can say to anyone that changes anything, and they would be foolish to comment on ongoing legal disputes, anyway.
most repos come back up after 10 days, I imagine, especially the ones taken down by unjust claims.
so, just because it's been 9 days with no communication means exactly nothing.
the law mandates this process, and GitHub must follow it.
