An anonymous reader writes: Twitter made a public stance in 2011 to remain a platform for free speech, having helped fuel movements such as the Arab Spring. This past week, however, Twitter is shown to have complied with Russian government demands to block a pro-Ukrainian Twitter feed from reaching Russian citizens, with Turkish government demands that it remove content that the Turkish government wants removed, and with a Pakistani bureaucrat's request that content he considers blasphemous and unethical be censored in Pakistan. Given Twitter's role in the democratic uprisings of the past few years, what do these capitulations bode for future movements? Will other platforms take Twitter's place? Or is the importance to democracy of platforms such as Twitter overblown?
