Sure, and telling a provider, even as a group, that continuing to do business with someone you deem undesirable is detrimental to their reputation is also legal. That's not what the EFF takes offense with. The EFF takes offense with a tier 1 ISP cutting off traffic from a provider because some of that traffic goes to KF.
I haven't seen the claim you speak of but I have seen the claim that Kiwi Farms has a history of doxing trans people for no stated purpose other than to implicitly condone harassing and bullying them into suicide. The doxing against Keffals led to multiple instances of targeted harassment offline and KF members positively responded to this while continuing to support the doxing.
If a book club mostly meets to discuss recent NYT bestsellers but occasionally serves to organize bank heists, it's entirely fair to describe it as seemingly solely existing to do bank heists because there are plenty of other book clubs that don't do this and this is its distinguishing trait.
