China censorship

What do Australia and China have in common? Apparently, it appears that the web filter projects for both, designed to keep children safe from porn, have the ability to be used to censor politically sensitive material. Hopefully, the Australian version (when I last heard it was undergoing testing) won't be installed on individual computers because when they've been testing this in China it apparently opened users to security risks - and drew calls from a Californian software company that that version contained stolen portions of their software. Curiouser and curiouser.
