Absolutely, America does seize domains with the assistance of local authorities[1] for crimes that are in prosecution. You may disagree with the reasoning for these crimes, or disagree that they are crimes at all, but US censorship works as a part of the legal system with well defined due process and remedies.
This is classic whataboutism compared to the outright corporateocracy of la liga's blocking and seizure.
