The title of the original https://www.heise.de/news/Deutsche-Datenschuetzer-draengen-auf-endgueltiges-Aus-fuer-die-Chatkontrolle-11282922.html currently talks about "Datenschutzbehörden", i.e. data protection authorities; but you can see in the URL that the article previously had a different title, which seems to be the one used for the translation to English, there's apparently just no better way to directly translate "Datenschützer" to English. :/
