Then let me help you understand.

Wikipedia:Wikipedia:Manual_of_Style/Writing_about_fiction

By describing what "really happened" and what "didn't really happen" in a work of fiction, you are describing it from an in-universe perspective. For example, if you say it's "canon" that Pinkie Pie can hang upside-down using her back hooves, that's an in-universe description. You ignore that it's a gag, and not to be taken as "what's real" or "what isn't real" in the fictional universe.

Treating things as "canon" lends to writing synopsis like a historical account and "filling in" gaps in continuity, both of which are in-universe descriptions.
