This is something that is endemic not just to ad-tech companies, but regular brick and mortar stores as well: it isn't enough to just be consuming, to actually be producing value for the business: they must monetize as many seconds of our attention as possible!
If I'm buying gas, I'm being served ads via the little screen. If I'm at the grocery store, there's ads plastered onto my cart. Buy something online? I get ads for unrelated products emailed to me in the weeks after, even if I didn't agree to be marketed to (I never do.)
It makes me feel like I'm going crazy, sometimes. And what's worse is it feels like there isn't an end in sight.
