Legally, the EU is claiming that if you do certain things which affect EU residents, then it will declare a judgment against you regardless of where you were when you did those things. This idea is not new and certainly is not seen as unequivocally wrong in law. If you produce libel against someone from another country, that person may sue you in their home country. That you performed the libel in another country is not generally seen as problematic to the libel laws of most countries. The US may refuse to recognize the judgment and you are fine as long as you do not travel to said country or a country with extradition agreements.
