What is the "Fair Ads" program for publishers, and how is it different from "Acceptable Ads?"

Acceptable Ads (used by some other ad blockers) often require advertisers or publishers to pay the ad blocker to get whitelisted, with no revenue share to the users.

Fair Ads (Pie’s approach) lets publishers pay the user (100% of it goes to the user) for allowing ads. Pie does not pocket that portion. This fosters a more equitable arrangement—publishers maintain ad revenue, users see fewer but more relevant ads, and they’re compensated for their attention.
