Fandom purchasing Gamepedia and moving everything onto Fandom Wikia was so awful. I'm so upset the Dota2 Gamepedia wiki is now on Fandom, and I'm sure many other communities feel that way for their own community run and community led wiki pages.

Not that I was particularly warm about Gamepedia either, but at the bare minimum I didn't feel like the page was all ads and no information. Fandom wikis are explicitly set-up to drive as many eyeballs as possible onto advertising and engagement, and are holding actually relevant information for the visitor as a hostage to get those eyeballs. It's information masquerading as a social media site.

The Runescape community convincing Jagex to cover the hosting costs and moving all their wiki pages to their own set-up has been such a huge boon for their community. It is super unfortunate that for many communities, the community-led wiki pages are a huge trove of information but the companies/games/groups these communities coalesce around have shown little to no interest in merely just financially supporting the endeavor.
