I'm not saying your wrong, nor am I saying "free speech bad", I'm saying something needs to be done to at lest protect children from ideas like, "Winston Churchill started WW2 and Hitler was just a victim".
Personally, I'd be taking issue, serious issue, if the plan by the Australian government was to block access to libraries and history books, but that's not what I see happening here, they're to do something about foreign propaganda poising kids brains and because the companies would never regulate themselves, they're trying to do something but it seems futile.
