But now people do, and it still works. How is this dissimilar to controlling the media in the past? Maybe can be more specialised, but superficially at least O don’t see significant content specialisation, rather the opposite, consumption herding.
Which I also think is overblown. The one thing that people can actually agree on is that dynamically setting sticker prices is bad, but nobody actually does this. There's less consensus on whether coupons (targeted or otherwise) are okay, even though they have the exact same effect (ie. $10 w/ $2 targeted coupon vs a Dynamic Price™ of $8).
