I am working with a visiting scholar from China, and part of my collaborative process is to use a shared document through the cloud based LaTeX service called Overleaf. The scholar I am working with said that she cannot use Overleaf because she is Chinese and that China doesn't allow "Google."
I know that there are Chinese researchers that use GitHub, for instance, so cloud based storage can't be completely out. It's hard for me to get a straight answer, since her English is spotty. I'm not sure where the connection between Google and Overleaf is coming from.
Is there a limitation on the usage of Overleaf and similar services imposed by the Chinese government?
