alt Hacker NewsRandom question: do you work with the new wikis to create some kind of license that prevents Fandom from scraping future changes back into their version of the wikis? Obviously the technical modifications can't translate, but it seems like it wouldn't be that hard for them to slurp most textual/markup changes back in and make it look like their version of the wiki is still alive…
When RuneScape and Old School RuneScape Wikis forked, the license was changed from CC-By-SA to CC-BY-SA-NC. As a result, all new changes come under the new license. To copy changes back to Fandom, they'd need to update their license to match and as I understand it so forfeit some of their ability to use so much advertising. I'm not sure if that license update was also applied to Minecraft or LoL, but it's a possibility.
The only use of CC-BY-SA-NC on Fandom I can recall is Memory Alpha (Star Trek Wiki) which was acquired with that license. There were some extra hoops to jump through to be able to advertise there - I think they granted themselves the ability to do so through Terms of Use that override the license.
