KF "only" archived and reposted the video and manifesto by the Christchurch terrorist. This is illegal in New Zealand and the police asked KF to release the data of all NZ users commenting on the video, which JM refused to do since it's an overreach and they legally run under an US entity thus don't have to comply. That didn't go well with the NZ law enforcement and got them delisted from there.
This is why people associate KF with Christchurch, however the terrorism act itself was not initiated by a KF user and anyone saying so is spreading fake news.
