It’s just like Gmail and Yahoo.
Talk about something in an email and a week later, miraculously, you have lots of ad space devoted to that item or class of items.
Don’t believe me? Write your brother about cat litter if you don’t have a cat. Or roofing supplies, or whatever. Turn them ad blockers off, and by next week you’ll have plenty of suppliers magically directed to those rented Google Ad payper click accounts....
No, it's NOT. It's MUCH MORE invasive than email! It's potentially eavesdropping on all of your private conversations in your own home! Sorry but I'm not so lazy that I can't turn on a light or the TV myself. If I want to order something I have the option of going online to order it or making a phone call. Much rather that than to have some "listening tool" always on in my house.
