I'm happy to see this, and hopeful that more wikis will follow suit. Things like the Minecraft Wiki, Wookiepedia, etc would be much better as self hosted sites rather than Fandom ones, and probably run significantly better too. But it makes me realise that we really need to support hobbyist/fan run services as much as possible if we wanted self hosting to be rewarded. Is there an extension or something that tries to block sites owned by large companies (whether they be Wikia, Alphabet, Meta, etc)?
