As far as I can tell, the facts are that the EU was canon (albeit on a secondary tier, literally) until the Disney reboot.
No, they just
said it was. In practice, it was freely contradicted by new movies and shows and kept having to rewrite itself to keep up with the changes. The movies totally overwrote the EU version of the Clone Wars and Republic history,
The Clone Wars totally ignored Karen Traviss's ongoing Mandalorian novels, and so on. Yes, there are fans that delude themselves into believing it was all consistent until 2014, but that's blatantly ignoring the facts. It just
pretended to be consistent as it repeatedly rewrote itself to conform to new movies and shows and quietly swept the old, contradicted continuity under the rug when it couldn't find a handwave to reconcile things.
"Canon" is just a word. Labels don't create truth, they just describe things that exist. Canon means the core body of work. If that core body freely ignores and contradicts its tie-in books, then sticking the word "canon" on them doesn't
make them canon, any more than writing "Ferrari" on a cardboard box makes it a sportscar. The word is meaningless by itself; it's the practice that matters.
Sure, I was thinking more that the DSC arrangement seems different then anything Paramount/CBS/etc. did before and it does make one wonder why a different tact was taken now.
I'm sure I've answered that question from you before. The only difference is that Kirsten Beyer is on the show's staff and thus it's convenient to use her as a liaison between the two branches of Trek that she's connected to.
And again, the goal is to improve the ability of the tie-ins to keep up with the show, something that the early tie-ins to past shows were not always able to do successfully because of the rapid changes that can happen early in a show's production. That does NOT mean it goes in the other direction. And we've already seen that it hasn't even worked -- despite their best efforts, both
Desperate Hours and the comic
The Light of Kahless have had elements that were contradicted by season 2 of
Discovery.
So it's really not fundamentally different from what's been done in the past. It's just a matter of degree, an increased amount of access and communication from the show to the books. But it still doesn't guarantee mutual consistency, because that's just not a realistic expectation given the moving target of TV series continuity.
On the other hand, if there's nothing but silence on the issue, kinda hard to prove or disprove.
That's the wrong way of looking at it. Tie-ins are
rarely canonical. It's almost impossible to
make them canonical unless they're from the actual creators of the original work. So the automatic default assumption should be that they aren't -- it usually isn't even a question.
It's best to think of "canon" as "the stuff from the original creators or owners." You'll almost never go wrong that way, because it's exceedingly rare for anything that isn't from the original creators or owners to be part of the canon.
Since the movie series was canceled, could it be considered canon? No real reason not to, given that Saban is silent on the issue and it's not like it's going to impede anything down the road or likely to get reevaluated.
If the question is whether you
personally want to count a story as "real" in your mind, then the word "canon" has
absolutely no relevance to that decision whatsoever. It doesn't matter in the slightest what label you stick on the thing. Just count it already and stop wasting effort worrying or arguing over what to call it.
Most of these things have multiple creators, including ones who come and go.
That's why "or owners" is part of the definition too. Creators hired by the owners of the property to continue the primary work are in a different category from creators working for a separate licensee to create supplementary works. The former is sort of like the heir to an estate; the latter are basically just contractors hired to work on the estate.
Heck, in the Star Trek Kelvin movies, the writing teams had mutually contradictory ideas on how the time travel accident worked and what changed it did and did not make to history (granted, neither was canonical, but still...).
For the five millionth time, whether something is canonical has nothing to do with whether it is self-consistent. Many, many canons are full of contradictions. That's not what it's about. It's about the consistency of the overall authorial voice and vision behind a work, not the consistency of individual plot details or factoids.
That honestly doesn't make any sense to me. I am weird, but still. I mean, pretty much anything in a franchise is canon until contradicted.
Not in a
franchise, because a franchise consists of the original work (which we nickname the "canon")
plus its derivative works like adaptations and tie-ins and merchandise.
And again, "canon" is a
noun, not an adjective. It's not a declaration of value or consistency or reality. It just means the original work that other things like tie-ins or fanfiction or adaptations are based on.
