You can still access wikis that are on the legacy platform but Fandom will not allow you to create a new wiki using the legacy platform. That is just a decision Fandom made.

There are other MediaWiki farms out there but they are all using a version of MediaWiki similar to what UCP uses. Fandom is actually very much behind the times when it comes to its MediaWiki version. Fandom's "competitors" have been on this newer version for quite a while now. In fact, some have already moved onto even newer versions.
