I think that’s at least partly explainable by how French cooking was so thoroughly adopted by European haute-cuisine in general - there are fewer specifically French restaurants because huge amounts of French cuisine became known as just general fancy cooking instead. I will say that when I have visited France, I have eaten exceedingly well without having to spend a lot of money

But yes, it is subjective. I do think it’s reasonable to say that France has a good reputation for food, though
