Ask HN: Ads triggered by WhatsApp “end to end encrypted” messages?
Just because that the messages might be sent end-to-end encrypted from Sue to Joe does not mean Meta cannot read them.Meta has control over the app Sue uses. So they could send them to Meta unencrypted in addition to sending them to Joe in an encrypted fashion.Or they just extract the relevant terms:Sue->Joe: "Hello Joe, I'm so excited! We are going to have a baby! Let's call it Dingbert. You're not the father! Jim is. I hope you don't mind too much!".Sue->Meta: "Sue will have a baby"Insta->Sue: "Check out these cute baby clothes!"
