Ad slots are often sold and resold through various exchanges, platforms and marketplaces. If each entity in this chain is liable if fingerprinting happens, then fingerprinting will quickly be just as toxic as other kinds of exploits and mostly disappear from the ecosystem.

For a site to be completely out of reach of the US/EU, all of the involved companies (site operator, fingerprinting provider, company paying for the advertising, ad network provider + the other middlemen involved in serving that ad) would have to have zero connection to the US/EU.
