That's because it is usually perfectly legal to lie about someone in the US and just call it "hyperbole" or something. Our libel laws are incredibly permissive in the US. See Elon Musk calling a guy a "pedo" repeatedly with zero evidence, because he pissed him off online. Although there were other issues in that case. The UK has way more strict libel laws than the US. If you lie about someone it's a LOT easier to get a civil judgment against you. Hency why a ton of magazines/newspapers have been successfully sued over libel whereas in the US this almost never happens.
