Walmart REALLY listens. I bought a few groceries IN STORE and about two weeks later I got an email with a list of items I purchased and links to review them. Now, I know what you're thinking, but I'm not enrolled in their loyalty program, and I don't have their app installed on my phone. The only way I can figure they linked my purchase to my email address is because I have previously logged into their website on my phone (via the browser) and of course my phone was with me during my shopping trip. That's some creepy shit.
Yeah, that would be much more plausible. As dystopian as Walmart is, I don't think they have phone sensors that can determine your device by just being in the store...
laughs in uBlock Origin + pihole (w/ a 700k+ single adlist) + nextdns on a container and redirecting all my inputs to my rpi 4 instead of my pc, while (also) under ufw
Considering I've never once been served an ad from either of them that I actually felt any reason whatsoever to click on.... No, I don't really think they are.
Either that or I'm the most unmarketable human being on the planet, which is plausible, but doubtful.
