One of the two Democratic commissioners on the Federal Communications Commission on Thursday slammed the Chicken Little attitude of the regulator’s chairman — pointing out how wrong he was in 2015 when he predicted gloom and doom under net neutrality.

In a direct 10-point takedown, commissioner Mignon Clyburn said Ajit Pai’s predictions were all false.

Pai, recently named by President Trump to be the chairman of the FCC, was a commissioner in 2015 when he predicted the Open Internet Order, known more widely as net neutrality, would be stricken down by the courts as illegal.

“False,” Clyburn wrote.

“The DC Circuit twice upheld the 2015 order and rejected all of the statutory interpretation arguments Chairman Pai raised in his dissent,” she added.

In his doomsday manifesto, Pai also argued that net neutrality would result in “slower broadband speeds.”

“False,” Clyburn countered. “Broadband speeds have continued to increase amid new investment by broadband providers.”

The move by Clyburn is a last-gasp effort to save net neutrality before Pai’s repeal proposal goes to a vote on Dec. 14.

With a 3-2 Republican majority on the FCC, Pai’s push to undo net neutrality is generally seen as a shoo-in.

Under net neutrality, broadband providers cannot discriminate against any content by giving its proprietary content priority.

Without such a regulation, broadband providers will be able to charge companies like Amazon and Netflix extra fees to guarantee speedy passage of their content through the distributors’ pipes.

Pai, in warning against adopting the 2015 Open Internet Order, also forewarned that “decisions about network architecture and design will no longer be in the hands of engineers but bureaucrats and lawyers,” a prediction that has proved to be nowhere near reality.

Clyburn’s last stand is mostly symbolic, however, as the repeal is expected to pass along party lines.

Pai has largely ignored the massive backlash he has received since introducing his plan to scrap the landmark rules last week, which would clear the way for service providers to charge for higher internet speeds and to slow access to some sites.

At a Washington, DC, event earlier this week, Pai insisted that the repeal would return the internet to a “light touch, market-based approach.”

The 44-year-old Pai also accused Twitter and other tech titans that have been vocal opponents of the repeal plan of being less than honest about the reasons they want to keep net neutrality alive.

“They might cloak their advocacy in the public interest, but the real interest of these internet giants is in using the regulatory process to cement their dominance in the internet economy,” Pai said.

A spokesperson for Pai did not return requests for comment.
