Your sarcasm is not appreciated. This is a serious matter, and that fact that you can't bring yourself to empathize with people being brutalized reflects very poorly on your ethical code. It's not meaningless at all to point out that actions have consequences, and in this case they are measured in human suffering.
If folks at GitHub believe they offer a product of value (which I suspect that they do), then the necessary corollary is that by offering that product to an agency responsible for a reprehensible abrogation of human rights makes it easier, cheaper, and/or faster for that agency to degrade humanity. To stick one's fingers in one's ears and claim that it is "apolitical" to continue to do business with such an agency is embarrassingly similar to the defenses that IBM executives must have made in the 1930's.
