Yeah French is just completely totalitarian and genocidal when it comes to regional languages and cultures. I love France, used to go to school there for short times, spoke and more or less still speak French, but for this there's no excuse.
The reason why the EU has fewer official languages than one country (Russia) is France. Once very flourishing languages like Provencal are practically dead. Until 1789 they were doing quite fine.
Then the revolution came along, and had a man named Abbé Henri Grégoire make a survey, which had him conclude that "while France was the language of civilized Europe, France itself had no more than three million 'pure' French-speakers [11% of the population], and many of them were unable to write it correctly."
Twice as many of its people (6 million) didn't speak it at all, and another 6 million barely.
Grégoire advocated eradicating all dialects and forcing everyone to speak only French, and some efforts were made in that regard.
Yet even in 1880, only 8 million (roughly 20%) spoke it fluently.
The country is destroying its own heritage and linguistic DNA. Almost all of that damage is from the third and 4th republic. In the 1940s, 1 million spoke Breton, now it's 170000, who are mostly elderly. Spoke a minority language in public? Well that's jail or fine for you monsieur!
As late as 1972 you have a president saying that "there is no place for minority languages in a France destined to make its mark on Europe".
Luckily France stopped being so aggressive about it a few decades (=not very long) ago but without active measures the damage will soon and in many places already is irreversible. ALL of the native continental languages except the main one in France are endangered. And France still hasn't ratified ECRML, and it never will.
It amended its constitution as late as 1992 to make sure of that: "The language of the republic is French". Any preservation measures are unconstitutional.
So a huge chunk of European heritage is going to die out in our lifetime. Remember "Deus lo vult"? That was old provencal. It's quite ironic that the party that's the most scared of muslim immigrants (Front national) is also the one pushing the hardest for a "zero tolerance policy": "Language and power go hand in hand" - Party manifesto of the FN.
