Funny you say that, the French are I believe the only nation to have come up with an institution specifically tasked with regulating the French language : l’Académie Française.

They have been around for almost 400 years, are rife with corruption, have produced a new version of the “official” dictionary every 50 years on average (and it’s not even a good one), a single grammar book that was so bad and full of ridiculous mistakes that the linguist community have been laughting at them continuously since then, and of the 40 members (for life) none has been a linguist since 1903. And although their enormous wealth has been subsidised by the taxpayers since its creation, the French governement has waited until 2015 to FINALLY require them to submit their accounting to the State accounting supervisor.

So you are very right, the French have foreited their linguistic rights indeed…
