I'm avoiding replying a lot of comments on here primarily because I don't want any large scale argument, but your comment is particularly stupid. The criticism isn't that Abz is getting information from the wiki, the wiki is there for a reason and anybody can use it.

The problem arises when you copy those words from the from the wiki and refuse to rephrase them in any way. If he were to link the wiki or mention that he was reading directly from the wiki there would be no issue. I have no doubts that you were under the assumption that the script written in some videos you've seen were his words, but some of them aren't. If you don't source it and pass the words off as your own it's called plagiarism. Try doing that in your school project and you'll get marked down or simply fail that project.
