Twitter and YouTube, which is owned by Google, have been more willing to embrace their roles in activism and unrest, Mr. Zuckerman said.
After the Internet was shut down in Egypt, Twitter and Google actively helped protesters by producing a new service, speak2tweet, that allowed people to leave voicemail messages that would be filed as updates on Twitter. Biz Stone, one of Twitter’s founders, used it as an opportunity to emphasize the positive global impact that comes with the open exchange of information.
When the Internet was back up, YouTube, working with Storyful, a social media news curation service, took the thousands of videos pouring in from the protests in Tahrir Square to help people access and share the information as quickly as possible on CitizenTube, its news and politics channel.
