Seems rather anodyne and doesn't seem to have much (or anything) that could be considered sensitive the fact that a state has installations like say RAF chicksands or the Lincolnshire poacher numbers station - both of which have Wikipedia articles.
Sounds like some french civil servant overracted - though unfortunately the French do have a nasty poujadist anti American strain that can come out at times.
I'm french i read the article , i dont see the big deal ? there is nothing special in that article. It's a stupid move from the french "secret" services as it will draw attention on something nobody cared about.
