When Twitter added its location feature and it turned out that political accounts with millions of followers are run out of Pakistan or India you have to be crazy to still deny the scope of foreign influence that is exerted over social media.
You see it with the rise in anti-semitism or Russia's explicit promotion of influencers targeting Western youth. Why on earth would we let our kids be brainwashed by foreign intelligence agencies? There is no reason to assume this is some "hidden agenda", this is as big of a public issue as the mental health of teenagers. The United States used to have media rules that limited foreign ownership in companies with a broadcasting license, and now 14 year olds get their political lessons straight from Moscow, it's ridiculous.
