To me it looks like our interpretation of "canon" is incompatible.
The way I see it "canon" is foremost "first comes, first serves", also to ensure respect for the intentions of the original creators. I think we all owe them that much, at least.
It seems that according to your interpretation of "canon" what is said last and alters, revises or overwrites previous canon is the neo-canon. Thus neo-canon prospers at the expense of previous canon and therefore has a somewhat ungrateful and parasitical nature, IMHO.
Most assuredly you're not alone as I can immediately think of 4-5 other BBS members that interpret "canon" the way you do.
But it's Star Trek and IDIC, so we can agree to disagree.
