They have the SEO juice to push out and replace dedicated wikis as the top result, even when there are long-standing dedicated wikis for the game/universe. Fandom wikis then typically have maybe half of the information from the dedicated wiki PLUS a bunch of intrusive ads. There's no instance that I know of where a Fandom wiki popping up for a community was a positive unless they simply didn't have one to start with.
