I'd be curious as to how one would define this "non-harmful" media? Seems like the linchpin to our future.

Look at mastodon. Absolutely nobody and nothing influences what you see except you. The only things you see are posts from people you follow, in chronological order. Emphasis on people, as opposed to AI generated celebrities selling boner pills to kids or whatever the hell is going on these days

Non-harmful means whatever the government wants it to mean.
