I would absolutely prefer my country to try blocking access to Github, Youtube or Wikipedia rather than Github/Youtube/Wikipedia to block particular content for it on its demand. In fact I would bypass the block anyway so it doesn't really matter practically but it matters a lot from the political point of view.

The governments/institutions demanding web sites to prevent their citizens from accessing particular content are modern day legal terrorists and tyrants and nobody should ever agree to negotiate such things with them nor volunteer to participate in oppressing their citizens.
