I'm not sure that's really fair, is it? I think you're confusing toxic fan behavior, which can take many forms, with what people like.
No, I am not confusing things. I have just seen so much ill will generated over the years by canon-angst that I have come to classify it as toxic in and of itself.
I have come to view canon and continuity like the rules and grammar of language - you follow it in general, but when it gets in the way, you violate it for sake of having a good piece.
