Big Tech grapples with Russian state media and propaganda

As Russia's war in Ukraine plays out for the world on social media, Big Tech platforms are moving to restrict Russian state media from using their platforms to spread propaganda and misinformation.

Google announced Tuesday that it's blocking the YouTube channels of those outlets in Europe "effective immediately" but acknowledged "it'll take time for our systems to fully ramp up."

Other U.S.-owned tech companies have offered more modest changes so far: limiting the Kremlin's reach, labeling more of this content so that people know it originated with the Russian government, and cutting Russian state organs off from whatever ad revenue they were previously making.
