Mass scale internet censorship in Russia also started with the premise of "protecting the children"
When you put in law that ISPs should adhere to some government-provided blocklist, this is already a game over. No matter how sane your government is. The government in 10 years might be vastly different, and the ability to control the ISPs is too alluring to not abuse
I'd rather live in a world where you could find words like "kill all russians", or child porn, or blatant propaganda than to live with the government censorship. I lived in Russia and the experience was nightmare. Who knows, maybe if the government didn't have the tools they had then the independent media would still be reachable by an average russian, the pictures of the pointless massacre would be public and the war would be over in a week
