Last week, the FCC's Wireless Telecommunications Bureau closed multiple inquiries led by former Chairman Tom Wheeler into the data-cap exemption — colloquially known as "zero-rating" — policies of various internet service providers, including AT&T, Verizon, T-Mobile, and Comcast.

Previously, Wheeler, who stepped down once Trump took office, oversaw a monthslong back-and-forth between the FCC and those ISPs. That resulted in the commission casting doubt on the legality of the zero-rating policies of AT&T and, to a lesser extent, Verizon. The concern was that such programs could be anticompetitive and stand in contrast to the net-neutrality rules set by the 2015 Open Internet Order.

Those findings are now moot. Upon closing the inquiries, the WTB said in a notice the results of Wheeler's investigation would have "no legal or other effect or meaning going forward."

Pai reinforced that finality. "These free-data plans have proven to be popular among consumers, particularly low-income Americans, and have enhanced competition in the wireless marketplace," he said in a statement. "Going forward, the Federal Communications Commission will not focus on denying Americans free data."

This is noteworthy.
