And the guy triggering it can be called anything, but he most likely wouldn't take money from a video game maker just to raise such a weird controversy. He's just taking any occasion he can to have media talk about him, and being on the extreme left, he is very much attached to the global positive feeling toward the french revolution (which he would probably like to see happen once again, with him being Robespierre, of course).
He is not extreme left either. He is from what was considered the "normal, banal" left in the 1980's, which is now tagged extreme just because they have not stopped to use the phrase 'class struggle'.
Now, the reason as to why the PS has accepted to make alliances with this party, which has always been in favor of a totally state-governed economy and against free market, and be fine with it, is an interesting question indeed (as opposed to the right wing parties who never put anyone from the extreme right in a government...for now).
Extreme left in France is parties like Lutte Ouvrière and NPA (formerly LCR). Besides, extreme left is very diverse, contains trotskysts as well as libertarians (who never, ever have supported the USSR, and some of them think that PCF militants are stalinists and socio-traitors).
You are mistaken, PCF is not considered extreme left in France. The fact that you are placed on the 'far left' on election results does not mean you are extremist. It means you are on a place of the political spectrum where journalists chose to put you, and that they have found no one more radical than they judge you are to put to your left and who presented candidates. But no one really labels PCF as extremists, except some people who have an interest in doing so: those from the right wing who wish to make a coalition with extreme right.
As for your parallel between PCF and extreme right in France (I think you refer to FN), I am truly sad that someone as smart as you are can fall in that kind of ideological trap. Look beyond the labels and actually read what the Front de Gauche proposes, it has nothing to do whatsoever with what the FN intends to do.
Not totally enduring though, as it's a lesson that seems to be very nearly forgotten by now. Mélenchon may get his wish.
(If they are, that's pretty impressive work by the Ubisoft PR department.)
The simpler explanation that someone at the Atlantic pays attention to French politics, saw these complaints, and spun it into an article for their American audience.

The French President's party isn't doing to well in the polls and I wouldn't put it past them to be this desperate (I see them as both winning in a sense here).
P.S. The Atlantic has no articles written about the numerous bugs from the game, even though it made it into several websites that usually don't cover video games. P.S. #2, The Atlantic is the website that produced that awful Scientology Paid Content Article[0]
