This is the case for "auction" based ad platform, I don't see how there is anyway to ever police this especially when they run the auction and have full view of all bids, essentially letting them perfectly price discriminate. Where are customers gonna go? Bing?

This and all the dark patterns to nudge the user to turn on "ad optimizations" without explaining what it does, anyone who has dabbled in google ads can surely attest



> This is the case for "auction" based ad platform,

Not stricly true for a second price auction. If you win the auction, you are know both the first and second place bid prices.


"... know both the first and second place bid prices."

Really?

Maybe for a public auction but done using Google's hidden "black box" system, how would you know that the second place bidder wasn't Google?


Google bidding in its own auctions is a separate problem from bidders' lack of access to top of book.
