France has a mechanism to try to stop this: the Académie Française [1] that publishes the official French dictionary. Rather than simply recording language as its used, they do actively try to steer it. They're most well known for trying to suppress anglicisms, e.g. in the early 2000s they pushed 'courriel' instead of 'email'. That one did not work out - email is much more common, and finally entered the dictionary in 2009 (to this day labelled 'anglicism' and discouraged over 'mél').

FWIW the German equivalent is much less prescriptive, it only weighs in on grammar / punctuation.
