Hah! They don’t have to. Many have “assistants” listening constantly, door cameras linked to central surveillance hubs, security cameras also linked to those hubs. It’s too late for most people - they took the bait. Hell, even the televisions record audio and send it back to the hub, and I’ve heard now that cameras are the new rage for them so we can “control the TV with motion”. Yeah, most are already cooked. I had to replace my old LG, bought a new one. I didn’t give it access to the internet. Even so, who knows if it’s still secretly doing it? And then there are our phones in which they swear they’re not tracking us. Yet, plenty of proof they are in fact recording our conversations and tracking our locations.
