Github is a platform that allows anyone to share my things openly. It also lets them contribute or perhaps even take ownership of the work if we agree it's better off in their hands.
Do you believe Github should preemptively filter content you are trying to git push? You're ok with me uploading all of your copyrighted photos to my GitHub page with the laws that exist today? Do you believe GitHub profits off of their popularity (driving more private repo and enterprise sales) built on a platform that allows users to upload copyrighted content? Is your answer going to be the same as the ones making judgements on GitHub while clutching this new legislation?
I'm perfectly fine with that.
