📝 Discussion Summary (Click to expand)

1. Surveillance pricing needs aban

"No, surveillance pricing is used to get the maximum out of the customer, not the opposite. This needs to be illegal." — emsign

2. Personalized price discrimination based on unrelated data raises fairness concerns

"The ban is specifically on adjusting prices per‑consumer based on data known/collected/stolen/assumed about the consumer." — 0x3f

3. Legislative proposals expose enforcement limits and unintended consequences

"Another limp‑wristed penalty. Why not something like \"$1,000 per dollar that you received as payment for prices in violation\"?" — clintonb
