They also mention Marvel comics in the article. Although, it seems a bit less concrete than that. These stories were written over the course of hundreds of years, and were often not really collaborating at all, right? Like, Lancelot's characterization can diverge pretty significantly depending on whether the author is English or French, haha...
Correct. Marvel has somebody in charge. A more apt parallel is fanfic... except that there isn't any "canon". It's all fanon.
In the Arthurian fanfic verse, a few authors get famous enough that they form a kind of accepted canon. You're likely to read Malory in school, because the faculty likes the Malory version.
Try telling your teacher that you disagree with their headcanon.
If you think there's trouble to be had when telling your professor that you disagree about what's canon for a mythos from 1000 years ago, you should not engage with believers on what's canon vs not about a story about a Jewish carpenter from, oh, about 2021 years ago. Definitely do NOT question if that story has somebody in charge.
