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.<p>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.<p>Or they just extract the relevant terms:<p>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!".<p>Sue->Meta: "Sue will have a baby"<p>Insta->Sue: "Check out these cute baby clothes!"
