 ** their gitlab.com render is shit for some reason, clicking on the ToC does not jump to headers properly, not sure why, IDs look correct
 ** one really cool thing about gitlab is that it can serve images from directly gitlab.com e.g. https://gitlab.com/cirosantilli/china-dictatorship-media/-/raw/master/Xi_Jinping_The_Governance_of_China_photo.jpg unlike GitHub which has the `raw.` subdomain: https://raw.githubusercontent.com/cirosantilli/china-dictatorship-media/master/Xi_Jinping_The_Governance_of_China_photo.jpg This makes it impossible to block the GitLab images without blocking all of gitlab.com, until GitLab starts a <<github-gov-takedowns,gov-takedowns>> of their own.

 The perfect solution might be to download all images and upload them to https://github.com/cirosantilli/media since GitHub content does not go through Camo, we have to see if such images don't fail to load as often.
