Zero-rating is the practice of providing Internet access without financial cost under certain conditions, such as by only permitting access to certain websites or by subsidizing the service with advertising. Commentators discussing zero rating often present it as a subtopic of net neutrality. While most sources report that use of zero-rating is contrary to the principle of net neutrality, there are mixed opinions among advocates of net neutrality about the extent to which people can benefit from zero-rating programs while retaining net neutrality protections. Supporters of zero-rating argue that it enables consumers to make choices to access more data and leads to more people using online services, but critics believe zero-rating exploits the poor, creates opportunities for censorship, and disrupts the free market.

Supporters of zero-rating argue that it enables consumers to make choices to access more data and leads to more people using online services, but critics believe zero-rating exploits the poor, creates opportunities for censorship, and disrupts the free market. Internet services like Facebook, Wikipedia and Google have built special programs to use zero-rating as means to provide their service more broadly into developing markets. The benefit for these new customers, who will mostly have to rely on mobile networks to connect to the Internet, would be a subsidised access to services from these service providers. The results of these efforts have been mixed, with adoption in a number of markets, sometimes overestimated expectations and perceived lack of benefits for mobile network operators. In Chile, the national telecom regulator ruled that this practice violated net neutrality laws and had to end by June 1, 2014. The Federal Communications Commission did not ban zero-rating programs, but it 'acknowledged that they could violate the spirit of net neutrality'. Since June 2014, U.S. mobile provider T-Mobile US has offered zero-rated access to participating music streaming services to its mobile internet customers. T-Mobile launched its plan called “Music Freedom” which would exempt users of T-Mobile from having to pay premium prices for access to music content; additionally, this content access would not count as part of an individual's cap, which is the limit they can reach before they are charged for data. In November 2015, they expanded zero-rated access to video streaming services. In January 2016, Verizon joined AT&T by creating its own sponsored data program, FreeBee Data, which 'enables content providers to pay a wireless provider to allow its subscribers to engage with or consume a piece of content without it counting against the customers' monthly allotments'. Sponsored data on behalf of content providers through AT&T or Verizon covers the costs for the viewers and attracts more consumers. Some people have characterized this as ISPs having created a toll-free service for online users. Advocates of net neutrality state that sponsored data 'allows well-heeled content providers to pay for placement to the disadvantage of smaller companies that can't afford the same luxury'. Verizon's FreeBee Data program which allows its own customers to access certain content, like ESPN and its video streaming service, for free along with any other relevant app access and the data will not count against their monthly caps. In this way, big ISPs discriminate against data and content from those who do not pay to have their content included in the FreeBee or other sponsored programs. Similarly, mobile network operators are also able to use the underlying classification technology like deep packet inspection to redirect enterprise-related data charges for employees using their private tablets or smartphones to their employer. This has the benefit of Toll-free / zero-rated applications allowing employees to participate in bring your own device (BYOD) programs. Zero-rating certain services, fast lanes and sponsored data have been criticised as anti-competitive and limiting open markets. It enables internet providers to gain a significant advantage in the promotion of in-house services over competing independent companies, especially in data-heavy markets like video-streaming. A service provider, who is offering unlimited access to their service, will naturally seem more favourable to consumers over one where usage is limited. If the first provider is the one restricting access, they are creating a considerable advantage for themselves over their competition, thereby restricting the freedom of the market. As many new internet and content services are launched targeting primarily mobile usage, and further adoption of internet connectivity globally (including broadband in rural areas of developed countries) relies heavily on mobile, zero-rating has also been regarded as a threat to the open internet, which is typically available via fixed line networks with unlimited usage tariffs or flat rates. Facebook and the Wikimedia Foundation have been specifically criticized for their zero-rating programs, to further strengthen incumbent mobile network operators and limit consumer rights to an open internet. The concern raised about how zero-rating can violate net neutrality is that when companies pay large ISP’s, then that ISP will prioritize that given platform over others. This gives companies who are able to pay a large sum of money to an ISP an advantage over others who did not pay the premium cost. This idea violates net neutrality as it gives large companies a leg up in comparison to their smaller, less known counterparts. Net neutrality is centered on the idea that all ISP’s treat data contents equally, yet with T-Mobile’s example of “Music Freedom”, net neutrality is no longer viable. The United States has not officially made a decision on the regulation of zero-rating providers; instead, adopting a “wait-and-see” approach to the matter. The FCC has therefore elected to examine on a case-by-case basis under a “general conduct rule” that “prohibits unreasonable interference with end users’ ability to select content and content providers’ ability to reach end users”. Days before the Trump inauguration, the Obama Administration FCC issued a report expressing concerns with T-Mobile, Verizon and AT&T and their sponsored data programs. The FCC’s Wireless Telecommunications Bureau found issues in wireless broadband services that vertically integrate their own affiliated programming, along with service providers allowing unaffiliated content providers to sponsor data. The report concluded that vertically affiliated broadband providers that zero-rate affiliated content most likely violate the general conduct rule.
