The inventor of the World Wide Web tweeted his support for net neutrality on Wednesday, writing that he created the network as “An open, permissionless space” made for everyone, not just those who can afford to pay.

His comment came as Democratic lawmakers pushed colleagues in the Senate to consider new legislation that would put the Federal Communications Commission’s decision to end net neutrality under review.

“I invented the web as an open, permissionless space #foreveryone. The FCC’s repeal of #NetNeutrality threatens to take that away,” wrote computer scientist Tim Berners-Lee.

“Tell the Senate they must protect net neutrality to keep the web open.” He also tagged Senators Lisa Murkowski, John Kennedy and Jeff Flake in the tweet-conservative lawmakers whom supporters believe may swing a potential vote on the issue.

Since establishing the World Wide Web, Berners-Lee has continued to work in the tech industry and is an advocate for internet accessibility.

In 2008, he founded the World Wide Web Foundation, which, according to its mission statement, is built around the idea that the internet is a basic right and a global public good.

The founder of the World Wide Web has been an ardent supporter of net neutrality.
