Cyberplace: Cyberchase's Lost Pilot

A couple of weeks ago, I was on MediaFire downloading Family Guy episodes. I extracted the ZIP and found something odd; it was a .avi, but it surely wasn't an episode of Family Guy. It was a Cyberchase episode though no title was listed, it just said "CYBERCHASE_LOST_EPISODE." I decided to click on this mysterious file; the Media player opened up, and the Cyberchase intro played. The quality wasn't the best, it was as if it was ripped off a crappy VHS tape than a low-quality video. 
After the intro played, it went straight into the episode. It wasn't a lost episode, I recognized it the first few minutes it began. It was the episode where the kids and Hacker were preparing for it to rain for 40 days and 40 nights. Anyway, I watched through it and after that, the credits rolled. During the credits, I was shaking my head, thinking, "Well, that was a waste of time."
I was expecting the Media player to close, but it went into another episode. No intro this time, it was just pure static for 5 minutes before it went into the episode instantly, with no transition whatsoever. It actually showed a title card, unlike the last one. It said, "Cyberplace: Pilot." ''Cyberplace''? I thought. It faded into the episode; it showed an early version of Matt, Jackie, and Inez. By "early version", I mean that their designs were totally different than the ones in circulation today.
Matt had a more emo-like look to him, Inez had no hair (it is mentioned in the episode she is dying of cancer), and Jackie was surprising unchanged. The episode was about how they got to Cyberplace, an early version of Cyberspace, and how they met Digit and stuff. It was exactly like the normal pilot; except for the changes in personality (for example Inez bosses Digit around, and often abuses him). One thing that shocked was, that Hacker said ''Fuck'' to Delete in the last part of the episode, where Delete fails to heed Hacker's orders.
The credits didn't show up, and it just went to the ending logos with Hacker's laughing. Something odd was that, Hacker's laughing was slowed down and seemed to be played in reverse. Something else odd happened; It cuts to a CG animation of Hacker cutting Digit's stomach open with a piece of broken glass with realistic blood gushing out while looking at the screen with bloodshot dilated eyes. His mouth doesn't move, but you can faintly hear him say "I knew this day would come!!!" with an echoey voice. You can also hear someone laughing for some reason.
The media player closed, and my computer shut down. I tried to contact PBS about the episode, but I always got faint whispers that sounded like Hacker's laughing. When I tried to open the file, but I always got a message reading "You're time isn't now". On Friday the 13th, I tried to look for the file and it was gone; I mean like really ''gone''. Like it never existed. I tried looking for that Family Guy torrent too, but it said it was deleted because of copyright from Fox. 
And one thing I'm confused is, why did Fox take down a file containing an episode of Cyberchase, the show isn't even made by Fox. I'm really confused; please if anyone saw this episode tell me what is the meaning of it. I mean...why was Fox involved with this?
