It looks as though the Netherlands Authority for Consumers and Markets isn't too happy with T-Mobile's zero rating. The company will have to pay a fine of $52,000 a day until it is in compliance with the law. Dutch regulators have declared that T-Mobile's implementation of zero rating violates that country's net neutrality rules. The Netherlands Authority for Consumers and Markets (ACM) has declared that zero-rating offers like T-Mobile's “data-free music” may negatively impact competition between online services. Zero rating has long been opposed by net neutrality regulators, because it gives select services an unfair advantage by incentivizing consumers to use specific content or services.
