Tardis does not, as has been pointed out above, deal with "canon" or "non-canon" stories. Instead, we speak in terms of whether an item is "valid" or "invalid" in the writing of our in-universe articles. That is, when writing an article about, say, the Sixth Doctor, do we believe that Terror of the Vervoids can be used as a reference?

We simply cannot declare stories valid on the basis of their "stupidity" or their challenges to continuity. Were we to do so, we'd be forced to call contradictory television stories invalid, and we have no mechanism for deciding which of the contradictory (but otherwise valid) stories were the more "correct".

Truth is, there are an awful lot of stories in all media, which challenge each other. As has been pointed out by many writers, this is the natural result of time travel.

So that's why we choose which stories to include in the writing of our in-universe articles by means of our broadly inclusive four little rules. And that naturally means your question is based on an incorrect assumption about our policies, and, as has been pointed out by other good people above me, a misapprehension about the nature of "canon".
