Twitter faces new criticism from Congress amid charges it briefly blocked net neutrality critics

Sens Ron Johnson (R-WI) and Roy Blunt (R-MO) sharply rebuked Twitter following reports that the website briefly blocked its users from posting links to a blog post that criticized the US government’s network neutrality rules. Twitter previously had described the mishap as a glitch, but Sens Johnson and Blunt still penned a letter that slammed the company’s chief executive, Jack Dorsey, for an incident that appeared to lawmakers to be “an affront to free expression.”

The confusing saga began on July 12, the day that Twitter joined Facebook, Google and other tech giants for an online rally in defense of an open internet. But those who sought to share the company’s blog post could not do so on Twitter. For a time, the site marked the link as suspicious and blocked new tweets containing it. That immediately led to cries of censorship, given Twitter’s public participation in the day of action in support of net neutrality — and on the opposite side of the debate from AT&T. A Twitter spokesman at the time said the link was “erroneously caught in Twitter's anti-spam filters” and quickly remedied the mistake. But the fracas still managed to reach Capitol Hill, where Sens Johnson and Blunt on Tuesday described the incident in a letter to Dorsey as “disturbing.”
