Despite Trump’s prolific social media presence, the president-elect hasn’t demonstrated any real understanding of tech issues—net neutrality included. As a candidate, Trump never outlined a technology plan or platform. His discussion of cyber security on the campaign trail and in presidential debates was muddled and at times bizarre. (Remember his comments on the Democratic National Committee hack? “I mean, it could be Russia, but it could also be China. It could also be lots of other people. It also could be somebody sitting on their bed that weighs 400 pounds.”)

Nevertheless, net neutrality advocates are preparing for a renewed fight, operating on the belief that Trump will work to dismantle the internet as we know it.

Trump’s main—and possibly only—public comment on net neutrality came in 2014, before he was officially running for president, in a bewildering tweet that seemed to conflate tenets of the open web with the Fairness Doctrine, a federal policy that required broadcasters to use airtime to discuss controversial issues of public interest—and to feature opposing views on those issues. (The rule was eliminated in 2011.)

Trump’s stance, incoherent though it may be, seems simple enough to parse anyway: the Obama administration advocated for net neutrality (and specifically for strong FCC regulation of net neutrality rules), therefore Trump opposes it. Plus, Trump’s a Republican; Republicans tend to oppose regulation.

There are other, more specific developments that have net neutrality advocates worried. The make-up of Trump’s FCC transition team is among the biggest clues that a reversal of federal policy is likely. His appointees include Roslyn Layton, Jeffrey Eisenach, and Mark Jamison, all of whom have argued against the existing net neutrality rules. Eisenach and Jamison have both worked for companies fighting the rules—Verizon and Sprint, respectively. The consumer protection group Free Press referred to Eisenach and Jamison as “industry operatives” who have “habitually opposed the communications rights of real people, prioritizing instead the monopoly-minded views of companies like AT&T, Comcast, and Verizon ... ignoring the many people who struggle to pay escalating costs to connect and communicate.” Eisenach didn’t respond to an interview request for this story. Jamison and Layton declined interview requests.

In tech circles, a grim future for net neutrality is treated as a certainty, despite Trump’s silence on the issue. “Trump hates net neutrality,” the tech news site Recode wrote the day after the election. Trump’s picks for FCC leadership are likely “to hand control of the internet back to service providers like Comcast and Verizon,” The Verge reported, citing scuttlebutt in Washington.

Larry Downes, a project director at the Georgetown Center for Business and Public Policy, says advocates’ concerns are overblown—in part because there’s “really is nothing to go on,” to discern what Trump might do. (Trying to predict what the president-elect has planned is like playing “the world’s worst game of poker because every card is wild,” he said.) Downes believes that Trump’s team wants to see the open-web flourish—just not under FCC rule. Legislation is one possible approach, for example, and he’s advocated for that path in the past. A common refrain among those opposed to the rules is that government oversight is likely to delay essential infrastructure upgrades that could be spurred by private competition.
