What's wild is I'm not even mad about this to some extent. Like personalized price adjustments just feels like better couponing. Its just the fact the majority of people's food needs are met by for profit companies means that the well being of their customers are not even on the table of shit they track for.
Worse yet, we KNOW they are selling this data and our privacy is 100% not a concern of theirs either.
If my local grocery coop, farmers market did this, and gave reasonable efforts to keep their systems local, secure, data lean, and optional. I wouldn't even be mad. This is none of those things and done, again, by people that would crush orphans for profit if there was a market for it.
