I see non-Chinese criticism of the Chinese controlled internet centered more around control of domestic information than I do about preventing the foreign garbage. We hear a lot about Chinese netizens having ing to use coded language to discuss topics like criticism of leadership, or concern about social issues, or their contributions as will be removed.

Western internet is full of crap, and manipulation, but you won't get censored for criticising the Government... I guess unless you are an American criticizing Israel (which is a newer thing, really.)
