However, federated things are accessible. The big names Facebook/Twitter/Youtube/Google are blocked, and the services below them. However it is a blacklist of blocked not a whitelist of accessible. Putting google analytics traction in a header of a federated blog, meaning it's actually not federated, is indeed a stupid pain. China internet is restricted, but it is only restricted 'enough' for the current power.
