You’re right, but they’re related.

KF has a right to exist. But if they want to be part of society at large, society owes them no great debt; they are welcome to remain insular and talk about their bullshit amongst themselves, or even host their own CDN mitigation service if nobody wants to work with them, but nobody is required to give them a platform to spew their odious content.

It has a right to exist. CF has the right to choose their clients. I really don't see your problem. If they want to exist, they can host themselves and/or use TOR.

KF has a responsibility to abide by the law. By extension, it has a responsibility to ensure its users do not use it to break the law. I support KF's right to exist, but not in this state.
