The opinions, often expressed in tweets, came fast and furious after Twitter revealed its revised censorship policy late last month.
Social-media users, who had just pushed back against ill-considered antipiracy legislation Congress considered, were quick to criticize Twitter. Stung by the backlash, Twitter pushed back, arguing that its new policy will actually increase transparency -- not censorship. To some degree, that's accurate.
Twitter already removes some content in response to legal requests. Until now, it was done so quietly and completely: Tweets would disappear from the Web on a global basis, with no trace or explanation.
Under the new guidelines, tweets would only be removed in the countries claiming that local laws were violated. Twitter users outside of those nations would still be able to see the tweets. For those in the affected countries, a gray box would appear instead of the original tweet, indicating that it had been withheld.
Notices of censored tweets would appear on the website chillingeffects.org. And there would be a technological work-around, including allowing users to change their country of origin setting.
Ideally, tweets would be deleted only for criminal issues like child pornography or for content issues like copyright violations. But with most of the world's governments repressing the press in some manner, many countries want to limit social media's ability to spur, and organize, social protests.
Twitter has recognized its unique role before. It postponed a scheduled shutdown in 2009 in order to be available during the height of Iran's postelection protests, and it formed a partnership with Google to try to work around the crackdown on social media during the Arab Spring protests in Egypt last year.
But now as Twitter's business ambitions grow along with its usage, it will increasingly face a fundamental decision in some countries: Does it operate more as a news media outlet or a communications company?
