China's sovereignty extends only as far as its borders. It has no legitimate say in the goings-on outside. GitHub is located outside of this domain, under the sovereignty of a nation that allows and condones its activity. It's really US sovereignty that's under attack here, if anything.

This is almost an argument. But when a given nation's citizens attack the sovereignty of another nation, and their own government declines to curtail such behavior, this qualifies as an implicit endorsement. That's why people call it "cyber-warfare"; what we observe here is a border skirmish with less than the usual quantity of gunfire. As I said earlier, I look forward to seeing who wins.

But GitHub has in no way attacked China's sovereignty, so as long as GitHub's servers are located within the territory of nations that allow their business to operate. If China has a problem with its citizens accessing content hosted on foreign servers, it certainly has the right to block access. If Chinese citizens then become perturbed due to their reliance on that foreign service, that's a Chinese problem, not GitHub's.

If I were to stand on a sidewalk outside of a church with signs saying "You're God is false, Heaven doesn't exist, you're going to die and disappear forever," and a parishioner decided to punch me in the face to stop me, they would be in the wrong, not me.
