Also, the new "gluten-free" diet fad scares me, and I hope this does not become yet another thing they use to fuel their illusion of health.
Too late...
As a coeliac also, I freaking love the fad. Back when I was first diagnosed around 2004, it was nearly impossible to find GF bread mix. Now, I can buy 6 different brands of ready-made GF bread within a few km of my house - 7 once they finish building the Aldi down the road - and the larger supermarkets even have an entire aisle of gluten free stuff.
I happen to live in a country where we've always had a strong lobby group for celiacs though, and what I see mostly after the diet-thing came about is that there's a lot more almond flour and things like that.
I suppose it's different in other countries, I will agree with you that new products arise that would probably not have come otherwise, but what scares me is the threat of not being taken seriously when you mention you don't eat Glute.
That being said, I was only diagnosed myself because of hereditary markers later confirmed by examination, rather than any obvious surface-level symptoms.
