pro—beijing people often remove content that is sympathetic to the protests — tear gas being fired, image of barricades and the like. they also add their own content. pro—democracy editors tend to add content to shift the balance or the tone of the article. but in my experience, the pro—beijing editors are a lot more aggressive in droning up this information. it�*s now unfixable without external interference because they are trying to rewrite history. while these editors may use state registered e—mails and vpns to get across the internet that�*s otherwise banned in china, john says it�*s not a straightforward situation of beijing ordering the edits. there seems to be an overflow of patriotism in china and these changes are being carried out by people loyal to the communist party, but they are not paid for by the government and they are not all based in china, either.
