Btw, I think it's pretty much accepted fact that smartphones do spy on everyone. It's the main business model of any big tech company. Google, Meta... They definitely have algorithms to tailor their targeted ads to someones personal profile. And per default they look at what you're doing online all day. Keep track of your location if they can... The one thing that's unclear is whether they use the microphone and also listen to your offline conversations. My main point being: Listening in with the microphone isn't that far off. If you feel uncomfortable with that, you might want to re-consider a few other things as well.
