I honestly don't know what you mean here. You just wrote that the word is meaningless if the "definition is so flexible that it applies to basically whatever the author wants it to[.]"
That is exactly what canon is.
When you write, "you" want to get rid of Tom Bombadil, what if Tolkien did? What if he, later, wrote him out of the story? Doesn't he have the right to decide what goes on in his world?
This is why I wrote that the issue is complicated- you can't have it both ways. You can't both say something *has* to be canon (Tom Bombadil) because the author put it in there, and then in the next paragraph, argue that the author has no control over canon.
I'm not saying he doesn't. There's just a cost to that change. It's up to whoever owns the IP to decide whether or not the cost is worth it, but this doesn't make the cost vanish. It's still there.
IMHO, this is what I dislike- the hybrid author/fan canon nerd internet empowerment theory. Which is to say- canon is whatever the author put in, as extrapolated by empowered nerds, and can never be changed or altered, unless said empowered nerds okay the changes.
(I don't mean to be harsh or reductionist, but that's exactly the type of straight jacket I was discussing. Midi-chlorians were terrible because (all together now) they were a terrible idea that made the story worse. Not because of "canon." But because they were terrible. Jar jar, even though he's canon, is also a terrible, terrible idea.)
Saying "it's a terrible idea" isn't an end to the conversation, because it doesn't articulate
why it's a terrible idea - because clearly not everyone agrees! Things can be terrible for many (subjective, somewhat arbitrary) reasons. Hence my "part of." This was one element of what people disliked about midi-clorians. Some people did not dislike it so much as others!
But that's it. You get people arguing over things (Peter Parker/Spider Man can't be Morales, because CANON) simply because they don't want change. Good stories are good stories, and can serve many purposes- enhancing, playing within the lines, or subverting the dominant themes of the prior canon. Canon isn't just a word that people use to say, "My version of this is what matters, and no one else can change it." Because what often happens is that, without you even knowing it, "good" changes to canon become ... canon.
When I say "My character's morality is like Batman's," that's a meaningless statement at this point in time. It tells you nothing about that character's morality.
When my DM says "Let's play Dragonlance!", how meaningless should that statement be? How much should it tell you about the heroes and conflicts and villains?

Part of why people hated midi-chlorians is that they changed the meaning of what Star Wars was... for them.
Exactly. Arbitray. Subjective. Personal.

The moment we are told he exists the story changed. "Canon" changed. This is what happens throughout all stories. All of them. Canon is constantly changing. Adapting, as the next thing is introduced. I think that's the problem right there.
At a certain point, one needs to stop putting paint to the canvas and call it "done," warts and all (typically for written works, this comes in publication).
That doesn't stop you from making a new painting. It does mean that you don't go back and keep tweaking the painting you have. No matter how many great ideas you have for improving
Guernica and making it more relevant and "with the times."
