Facebook and YouTube are allowing themselves to become tools of Vietnam’s “industrial-scale” attempt to censor information and harass government critics, in an “alarming sign” of how technology giants increasingly operate in repressive countries, Amnesty International said in a report published on Tuesday. Al Jazeera reports that the 78-page Amnesty report documents the “systematic repression” of peaceful online expression in the Southeast Asian country, including the widespread “geo-blocking” of content seen as critical of the authorities and the imprisonment of a “record number” of activists who are serving jail time for their online work. Groups affiliated with the government are also accused of using the same online platforms to target and harass users into silence and fear.
