I think by just saying “French” people will be more interested in trying it. Not because its French but because it is different and, after all Greek yogurt is so 10 years ago.
I think if it sounds exotic people will buy it because it is new and they saw it on TV or read it on a blog as the new best thing. Chipotle, Sriracha, “insert your ethnic flavor here”, etc.
I actually got a sample of this yogurt for free at my grocery store a few months ago and found it very good (better than yoplait and chobani). I never cared to research the brand/company and am still buying it from time to time. Very creamy, sweet and in different flavors.
