"What Digicel is doing — turning ad-blocking on by default, and charging advertisers a fee to get through the filter — might fly in the Caribbean countries where it operates. But it's less clear that it would work in the United States, said Marvin Ammori, a net neutrality lawyer and activist.
"While not everyone loves ads, having carriers act as toll-booths for ads doesn't further user-choice, and would clearly violate our rules," said Ammori."
