No, the marketing was perfectly clear. It's just that fandom persistently and infuriatingly fails to understand the fundamental fact that the most fundamental definition of "canon" is "the stuff that isn't tie-ins." Tie-ins are not canon by default. That should always be assumed to be the normal, expected case. The marketing never said these books were canon, so there was no reason to assume they were. No one should ever, ever expect tie-ins to be canon, so unless it's explicitly stated that they are canon, then they are not.
I have tried backtracking the sources where I had read the original interviews in question. Either I'm misremembering what I read or I was reading different sources, given that my memories are not matching that much with the printed word. It's also possible that I subconsciously blended them with in my mind with Star Wars, which uses a similar model of coordinating the tie-ins with the movies except that non-movie installments are also canonical.
The books expand knowledge of the show's world because the person who wrote the books was talking to the people who wrote the show, and thus the book is able to express ideas that are part of the show's writers' thinking but that they didn't have room to put in the actual show.
Fair point, but I guess that putting in a source that's not considered to be part of the "official" account (and adds ideas from the author) makes it a curiosity at best. Kind of the old writer's adage if it's off-screen (off-page, off-panel, whatever), it doesn't count.
Sure, yes, the makers of the show could contradict those things in the future, but one thing canon obsessives never understand is that canon itself can be contradicted just as easily, as when DS9 ignored basically everything TNG's "The Host" established about the Trill, or when Dallas retconned an entire season into a dream. That's why canon vs. not-canon doesn't really matter. All fiction can be rewritten. No fiction is any more "real" than any other fiction. "Canon" is nothing more than an attribution of the authorship of the fiction, whether it comes from the creators/owners or somebody else.
Huh.
The marketing did nothing to indicate this novel would be canon, and I was never under the impression that it would have been in any case. Some fans leapt to the wrong conclusions based on the unprecedented level of coordination with the show's writing staff, not realizing that that coordination does not mean the same thing as being canon.
Okay, good for you.
What is there to clarify? Star Trek novels are never canon and have never been canon, and at this point, actually saying so would be stating the obvious, like saying rain is wet.
As the IP owners maintain the right to say what is considered canon and not canon, it was possible that things would change (e.g. pre-and post-Disney Star Wars). (I also recall that weird thing where the Kelvin Timeline movie makers were basically saying that they thought the video game and comics based on their movies were canon -- never minding the irreconcilable continuity errors in them -- but they didn't quite feel they could proclaim that due to tradition. So, it wouldn't've been the first time that the Powers That Be considering upending the old rule.)
Look, I really don't want to get into a fight over this. What is what is. Some of us are just trying to catch up.
