User blog comment:Brandon Rhea/Wiki domains will be changing from wikia.com to fandom.com in early 2019/@comment-33688999-20180819231702/@comment-31863794-20180820003102

To compare changing a site domain to be more consistent with the FANDOM brand to trying to be a social media site is, frankly, a very invalid comparison. The main focus of FANDOM will still be wikis and information. The URL change will change nothing about how the site currently runs.

As for wikis like the one you mentioned, Brandon Rhea has already said that Staff is looking into potential solutions for those wikis and I think it would be best to wait and see what they have in mind.
