An unprecedented spree of policy changes and carveouts aimed at protecting Ukrainian civilians from Facebook's censorship systems has earned praise from human rights groups. But a new open letter addressed to Facebook and its social media rivals questions why these companies seem to care far more about some attempts to resist foreign invasion than others. In response to the Russian invasion of Ukraine, Meta Platforms, which owns Facebook and Instagram, rapidly changed its typically strict speech rules in order to exempt a variety of posts that would have otherwise been deleted for violating the company's prohibition against hate speech and violent incitement. The rule change ... included a rare dispensation to call for the death of Russian President Vladimir Putin, use dehumanizing language against Russian soldiers, and praise the notorious Azov Battalion of the Ukrainian National Guard, previously banned from the platform due to its neo-Nazi ideology. In a statement signed by 31 civil society and human rights groups ... criticism is directed squarely at American internet titans like Facebook. "We call for ... equal and consistent application of policies to uphold the rights of users worldwide," reads the letter. "Once platforms began to take action in Ukraine, they took extraordinary steps that they have been unwilling to take elsewhere. From the Syrian conflict to the genocide of the Rohingya in Myanmar, other crisis situations have not received the same amount of support."
