Tony Romm, writing for Recode: FCC Chairman Ajit Pai thinks everyone from Cher to Twitter has it wrong when they say that his efforts to roll back the U.S. government's existing net neutrality rules will spell the death of the web. Instead, Pai said during an event in Washington, D.C., on Tuesday that tech giants could pose the greatest threat by discriminating against viewpoints on the internet. "They might cloak their advocacy in the public interest," he said, "but the real interest of these internet giants is in using the regulatory process to cement their dominance in the internet economy." The surprising rebuke came as Pai forged ahead with his plan to end the net neutrality protections adopted by the Federal Communications Commission under former President Barack Obama. Those rules subject broadband providers like AT&T, Charter, Comcast and Verizon to utility-style regulation, all in a bid to stop them from blocking access to web pages, slowing down connections or prioritizing some content over others. [...] He didn't spare tech companies from that criticism, either. Companies like Facebook, Google and Twitter -- speaking through their main Washington, D.C.-based trade group, the Internet Association -- have urged Pai to stand down. In response, Pai sought to make an example of Twitter. He specifically raised the fact that the company at one point prevented a Republican congresswoman from promoting a tweet about abortion, only to change its mind amid a public backlash. "Now look: I love Twitter," Pai began. "But let's not kid ourselves; when it comes to a free and open Internet, Twitter is a part of the problem. The company has a viewpoint and uses that viewpoint to discriminate."
