Just because I won't read the DBM fanfiction, doesn't mean that levels of canon or more or less clear. They exist. It's canon, my prerogatives aside, same with anyone else.
No official DB source has come out and said what is canon, what isn't, how is it determined and if there several levels or not. And only the people actually in charge of the franchise can define and establish what is canon and what isn't, not the fans. Fans only have opinions and, in the absence of an actual establishment of what is canon and what isn't by the people in charge, guesses.
Salagir just happens to have a different opinion than yours about what is or should be canon as seen in DBM's faq page: http://www.dragonball-multiverse.com/en/faq.html
What is "canon"?
We define canon as anything that happened in the original manga. Non-canon is any addition from the animation or other stories. It concerns scenes, but also characters or techniques.
DBM adds elements to the story while following DB canon. It also takes elements from the animations and films, but modifies some of them.
Usually when following the films, we take all the information, but sometimes change things to keep consistency with the manga.
For example, Broly, who isn't "DB canon", is "DBM canon" but he isn't the one from the movies, and his story is different from the movies, too.
You should notice that the folks in DBM even say "we define" instead of just saying that "canon is". That seems to show that they are stating what their idea/opinion of canon is, not that, somehow, they are the ones to objectively define what canon is in Dragon Ball.
The issue here is that you have your own idea of what is canon and what isn't and it doesn't match Salagir's, but you aren't the one who defines canon. Only an official source that can actually define and establish canon and none has done so.
Preaching to the choir, because I said that: we agree-his webcomic, his rules. However the moment someone says "Oh, they are following canon manga faithfully." Well, no he isn't. He disconnected with the manga at that point, he doesn't follow the manga faithfully. Whether you accept the guidebooks or not, they still exist and will continue being tied to the manga canon.
As is demonstrated by the link to their FAQ page, they don't say that DBM is "following canon manga faithfully". In fact, they fully admit they are including things in DBM that they don't consider canon. So, I don't get your point.
