For me, it's the surveillance infrastructure per se. My main curiosity around these bills is to what extent surveillance pricing–versus ad targeting–drives the economics of those systems. (My prior is not much.)

Surveillance pricing defenders claim that surveillance pricing is better because it works both ways--it might offer a higher price to someone who is desperate, but someone who is likely not that motivated might get a sweet deal. I highly doubt that. A highly-advertised, transparent discount or sale is how you sell to someone who is not that motivated. Surveillance pricing is how you (secretly) extract as much money as possible from the desperate.
