Outgoing Twitter CEO: 'Regulation is a threat to free speech'

Twitter's outgoing CEO said that government rules endanger free expression. “I will say directly that I think regulation is a threat to free speech,” Dick Costolo said, when asked whether there might be merit to regulating Twitter like a utility. “I can’t think of an example where regulation didn’t have unintended consequences and I’m unable to conceive of a regulatory body that will be swift enough to deal with the constantly evolving issues of ethics, communication and technology. I just don’t think it’s possible.” Costolo's last day at Twitter is July 2.
