>But the authorities and the justice system seem unwilling to do so
To me sounds like a conspiracy theory. If their crimes are so unquestionable and clear, it should be pretty easy and straightforward to prove it in a court of law. The other alternative being, of course, that there is no crime happening here, at least under the US law, and their actions, as tasteless and despicable as they might be, are covered under the american law and KF opponents are using corporations to censor legally protected speech.
I would like you to pay attention to the word "seem", which describe how their action - or lack thereof - appear to a third party, especially one which has been subject - and continues to be subject - to said "tasteless and despicable" actions, and to avoid jumping to conclusions.

That hardly sounds like the only other alternative. Even without assuming the malice of some hypothetical "conspiracy", it might be the case that
(1) the crime isn't happening here, on US soil, and thus the relevant authorities lack the power to pursue it (see also: spam call centers located in foreign countries);
(2) whoever is tasked with pursuing said crime has other, higher-priority crimes to deal with, and decided that the potential pay-off was not worth the cost of prosecution (see also: the whole US justice system);
(3) the prosecution is waiting to build a stronger case;
(4) it is not clear who should prosecute who (see also: diffusion of responsibility);
(5) the file was lost;
(6) the file got eaten by a grue;
(7) any other reason for why a large and complex machine might turn out to not be effective in dealing, in a timely manner, with a loose group of people who gather on servers hosted on foreign soil, which are not "KF opponents [...] using corporations to censor legally protected [sic] speech";
