The craziest thing I’ve ever seen with targeted advertising (on iPhone) is when I was vacuuming the room one day & as soon as I finished & opened Safari, was seeing ads for Vacuums
I hadn’t even ever said the word ‘vacuum’ - iPhone literally seemed to have cued the sound of the machine in the background. And mind you it’s an iPhone 7 with few apps & not some Pro Max future phone ..
From that moment I’ve been convinced 100% microphones listening, cameras probs watching.
