At some point, blocking CDNs at IP level becomes too much of an economic burden on a country to be feasible. We've seen an unwillingness by the Chinese to block access to GitHub; presumably this means Fastly (their CDN provider) is safe for a while.
Did you know that Russians had github blocked for several days? Anyway, you're talking about counter-censorship warfare. Yes, some of those measures will be somewhat effective sometimes, but the costs (not necessarily even monetary) are actually quite substantial, and it's definitely not for everyone.
