What I don’t understand about these projects is why can’t we both have them and protect the children
Think of this as closer to Signal than to a social media platform. It’s a protocol, so there’s no saying that you couldn’t build a social media site with it, bit for now the demo app that I saw today is just chat. The parties involved share public keys with each other, and from then on, everything is encrypted so that only those people in the chat can read it.
With that model, censorship is not really feasible. If you’re one of the perks in the conversation, you can say “guys, that’s gross, stop” or send screenshots to the cops or whatever, but that’s about it.
Ultimately, if the only way the Authorities have of acting against terrorism/pedophiles/etc is by infringing everyone in the county’s right to privacy, they’re doing a shit job and need to be replaced.
