Why should Github take on unlimited liability for someone else's code? If a judge agrees that blocking this anti-circumvention technology is illegal (something the DMCA does prohibit), and Github had refused to take it down (which means they don't get safe harbor), then Github is the first-party that is liable for distributing that illegal technology, probably many millions of times. When you start taking statutory fines and multiply them by millions, you end up with numbers that would put Github out of business overnight. Is that beneficial to anyone?
