Nope never heard of it before. Thanks for the heads-up!
I'm sensing that this is just one of the FUBAR things going on during the Directorate. Americans notice it since they were directly involved, while in France, where everyone and everything were getting screwed by corruption, it's getting lost in the static of the history of the Directorate. The strong man was Paul Barras, who pretty consistently gets described as "corrupt and amoral".
Which would give an incling of part of why people were happy with a military strong-man coup d'état in Paris in 1799. If Napoleon hadn't made it, the Jacobins were preassuring Bernadotte to make one.
