How much has the LET meddled in Chadwick's storyline?

Neurophyte, Toorima, Agent Skinner, the vamp rebellion, etc... from what I've heard, all these happenings (I use "happenings" instead of "events", because that sounds more general and isn't limited to the actual in-game events) have been invented by the LET. As far as I know, Neurophyte was a side-story anyway, but Toorima is the backstory for Veil and has been dealt with at her introduction a couple of chapters ago. Agent Skinner was the predecessor of Agent Pace. Although I wasn't there, I suppose those story elements have some relevance to the present.

Therefore, I'd like to know which parts of the Monolith story were original and which ones were attributed to the old LET when I'll be reading Stack's or Cloudwolf's storyline summaries in the future. Could anyone give me specific information about that?

Thanks in advance.

I think it is apparent that the Wachowski brothers sold out. This franchise is no longer their own, other than the checks they receive. I don't think MXO has anything to do with The Matrix anymore. Imagine if I had to tell someone my sales pitch for MXO...

"Hey man, you should play Matrix Online."

"Cool. Can I be Neo?"

"No, it's not like that. It's an MMO."

"Well, can I meet Morpheus?"

"No."

"Why not?"

"He's dead."

"Oh. What about Niobe?"

"Naw, she's a *CENSORED*. You wouldn't want to meet her. But you can meet, uh, Silver or Pillsworth."

"Who?"

"Uh, nevermind. But you can kill Tengu with me."

"Kill what?"

"Yeah, you load Hacker. It's like a Wizard."

"What? I don't want to play a Wizard. This isn't like medieval is it?"

"No, it's Matrix!"

"Doesn't sound like it."

"No... No, it doesn't."
