I really love this word: Schlimmbesserung
It originates from German, Schlimmbesserungen: bad improvements
-making sth. worse by trying to make it better
-An intended improvement that has the opposite effect (the adjective schlimm can mean anything from “bad” to “malicious”; the noun Besserung means “improvement”–literally “betterment”) source
Today there are so many supposed improvements that actually make things worse. There are so many.
For example the Toronto Star changed their online site to a smartphone design. I use a PC and there was so much wasted space that I decided to not go back. Schlimmbesserung strikes again.
