Mark Zuckerberg, in his appearance on Joe Rogan's podcast, specifically noted this as his goal for falling in behind Trump. That Trump would be the big-stick man that would protect Meta and other cos from foreign interference. Where "interference" is anything restricting that American exceptionalism "do anything we want, however we want".
Only then Trump started a trade war with quite literally the entire world -- aside from, predictably, Russia -- and now he holds, as he likes to say, no cards. The EU and anyone else can do whatever they want and Zuck and co can cry about the millions they wasted trying to buy a protection racket.
Of course Meta could just withdrawn from the EU. I wish they would withdraw from Canada. Their garbage misinformation platform is a massive net negative for humanity and has offered nothing but harm for the planet.
