not that i'm quite informed on the subject, but the way I think it is an attempt on preserving the language, and the French culture. The fact that the gvt is paying the bill makes sense, as 'preservation of the language', falls as preservation of heritage, such as national monuments, parks ...
I fail to understand why so many of u are prone to lauthing on the French effort of preserving their language, especially since it's close from "two millenium old".
It seems only a question of time before English takes over, and France already had to ban obviious words such as 'email' and create the French word 'emele'. As ridiculous as it seems, the effort can be understood.
Imagine that spanish becomes the dominant language in the world, and that your kids start to implement spanish words in their sentence, you would probably start a "wait a minute, that's not quite the legacy of our founding fathers, what can we do about it?"
