The only thing more rage-inducing than getting stuck in a game and needing to Google the information I need... is finding that information on a Fandom Wiki composed of 90% ads and 10% useful content. Especially since I'm usually searching for that information on my phone, due to not all games handling Alt+Tab particularly well, and Fandom is somehow even worse on a phone. I have genuinely had moments where I've just closed a game and stopped playing because the information I need isn't in the game but has to be found on a Fandom Wiki.

SEO wars only go so far when the user experience on Fandom is so awful that plenty of players would rather scroll down to use the #2 entry in the search results if it means not having to click a Fandom link. They'd only need a few occasions when the #2 entry is a better experience than using Fandom, and they'll start using the independent Wiki purposefully.
