"People are buying into" is a mis-statement, IMO.
I hate advertisements. I loathe them with every fibre of my being. I'll do almost anything to get rid of them. Multiple browser addons, a pi-hole, using a browser instead of an app, modem and router tweaks, whatever it takes.
But the data collection? I don't care at this point. It's absolutely everywhere and totally unavoidable, short of living off-grid in the middle of nowhere. It's in the software, the hardware, the services, the organizations. You cannot escape it.
Yes, it sucks. But it's just part of living in a modern digital society now. It could be better but you can't avoid it.
Hell, I use an app on my phone to track my driving so I get an insurance discount. It's one drop in an entire ocean of data collection that I can't see or hear or taste, but the money saved is very real in my pocket.
