As @T.E.D. suggests this kind of things is better understood from the inside. so here is how I see it from Paris.
President Sarkozy suddenly felt a hurry to push a so called "Armenian Genocide" law just before the last presidential election in order to rally the Armenian community which is quite influential in the French microcosm. That didn't help him to stay in for a second term, as you well know, but he gave probably little thought to the fact that that would nevertheless harm the French-Turkish relationship.
There is also probably some inward looking attitude of the French Right with regard to the adhesion of Turkey to the European Union and that might also have counted in Sarkozy's cunning plan.
Add to this the now well documented propension of the French intelligentsia to lecture the world and take a moral high ground regardless of its own track record in North Africa and elsewhere and you've got petty much the whole picture.
As for me, I've worked for Turkcell like ten years ago and I must say I was very impressed by what I saw and how dynamic and dedicated my young colleagues were (some of whom, I'm still in contact with). But I doubt this is well understood everywhere in today's France.
I don't think Turkish people should answer emotionally to this kind of events. I'd bet that one will probably witness less arrogance and misunderstanding in the future because people travel more and new generations on each side will take a more critical look at the sins of their respective ancestors.
