disimprovement
Change for worse
Disimprovement is the opposite of improvement—a change that makes something worse rather than better.
The word carries a wry or ironic tone, often used when someone's attempt to fix or enhance something backfires: The new software update was a disimprovement.
It suggests deterioration dressed up as progress.
