Huh? The google example is about content being available in public, essentially the equivalent of someone posting dirty / embarrassing pictures in a public square and needing there to be a way to take them down. That sounds pretty reasonable. The encryption example is about being able to intercept private communication (never mind outlawing math) because someone could use that private communication for something illegal. The two examples have nothing to do with each other IMO.
