Tupka217 and Fandyllic hit most of the points. However, some of the replies are a bit long.

TL:DR

The upgrade of the MediaWiki engine is a very much welcomed change for most users. The upgrade, as well as realignment to standard extensions bodes well for future maintenance and upgrades. Unfortunately, this comes at a cost. Because Fandom had previously been building more and more custom extensions for its outdated MediaWiki engine, it is now impractical for them to rework those extensions to work with the new MediaWiki. As such, a decent number of features that Fandom users have gotten used to over the years will be lost. The effect for users is a sudden and major change to the platform's appearance and features. Other wiki hosts, including Gamepedia, have been gradually introduced to this new layout over the course of years while Fandom remained stagnant. That is why the Gamepedia-only users have a hard time understanding why Fandom-only users are so upset about UCP.
