Those people arguing over who is at fault for this are missing an important point: Toei didn't pull the streams because one of them leaked, it pulled the streams because Funi's security was so bad (which they discovered because of the leak).
Let me say this in another way: Assume no one knew about this little "trick" to download the episodes, and no episode was uploaded to a torrent.
Now, 3 days ago, an employee of Toei animation who was tasked with checking out Funi's site discovered that it was possible to download episode 403 early. He reports this to his boss, and guess what: The exact same thing would have happened. The streams would have gone down, funi would have the simulcast postponed indefinitely, and we'd all be sitting here going "what's going on?" instead of arguing over whether the leaker should be shot, hanged, drawn and quartered, lethal injectioned, or given a medal of freedom.
The reason Toei got mad wasn't because someone leaked the episode early, that was just how Toei ended up finding out about it. It was because Funi promised them their site was safe and it wasn't.
