"Pay us for indexing our sites!"

"We don't want to engage in that transaction on those terms; if you wish, we will stop indexing your sites"

Then the French gov't steps in and effectively legislates that Google is legally obligated to engage in a transaction on the terms of the other party (and pulling out of the transaction is not an option). As I recall, the end result of this extortion was Google paying ~$70 million in what was effectively a protection racket (where the nominal purpose was to set up a fund to help French newspapers enter the digital age).
