On Tuesday afternoon, while most people were focused on the latest news from the House Intelligence Committee, the House quietly voted to undo rules that keep internet service providers — the companies like Comcast, Verizon and Charter that you pay for online access — from selling your personal information.

The Senate already approved the bill, on a party-line vote, last week, which means that in the coming days President Trump will be able to sign legislation that will strike a significant blow against online privacy protection.

The bill not only gives cable companies and wireless providers free rein to do what they like with your browsing history, shopping habits, your location and other information gleaned from your online activity, but it would also prevent the Federal Communications Commission from ever again establishing similar consumer privacy protections.

The bill is an effort by the F.C.C.’s new Republican majority and congressional Republicans to overturn a simple but vitally important concept — namely that the information that goes over a network belongs to you as the consumer, not to the network hired to carry it. It’s an old idea: For decades, in both Republican and Democratic administrations, federal rules have protected the privacy of the information in a telephone call. In 2016, the F.C.C., which I led as chairman under President Barack Obama, extended those same protections to the internet.
