Fandom was started in 2008. So that is 10+ years of legacy content before FishTank posted that blog (as opposed to less than 1 year since the blog). Even if you ignore this fact, it still depends on what the local wiki wants to do; as everyone else already explained. Some wikis use the category page to describe what does/doesn't belong in the category and why. They may also use it to describe the purpose of the category (for maintenance categories) and/or preferred methods for adding the category. For instance, on the wiki I admin, most pages are added to categories automatically by templates (as opposed to manually adding them to each page). - Edit:

Also remember that Gamepedia just recently became part of Fandom (around December 2018) and uses a separate platform. Although FANDOM wikis may have received this category update, it is not clear if Gamepedia wikis have an equivalent behavior.
