“Social-media companies shouldn’t take on the job of censoring speech on behalf of any government, and they certainly shouldn’t do so voluntarily,” said Danny O'Brien, international director of the Electronic Frontier Foundation in San Francisco.
Attempting to set speech restrictions online is a slippery slope, he said.
“Who defines 'terrorism'? Does Facebook, for example, intend to enforce its policies only against those that the United States government describes as terrorists, or will it also respond if Russia says someone is a terrorist? Israel? Saudi Arabia? Syria? The same questions apply to the speech that might be targeted," he said.
