On one hand, there are a lot more gluten-free products on supermarket shelves, all of which are legally required to be certified gluten-free. So big win there.
On the other hand, restaurants and chefs aren't taking requests for gluten-free food seriously, because there's a good chance it's just a fad dieter.
My experience has been the opposite. My wife is gluten-intolerant, and we find that most restaurants are knowledgeable and follow best practices. They have separate prep stations when feasible. They change gloves. Some even have separate menus. I don't know if ignoring a food allergy request is illegal in some jurisdictions, but doing so certainly leaves restaurants open to lawsuits.
For lot of allergics out there you can't even entertain the thought of eating out in a restaurant because of cross contamination (peanuts etc).
Being food allergic myself it has forced me to eat healthy and avoid crap food. Having a muscular ripped body is just one of the benefits.
I've found packaged salad that contains gluten because the vegetables were on a conveyor belt dusted with wheat to keep the salad from sticking.
Flour is used to thicken. If it has a sauce or gravy, it was probably thickened with flour. If it's a soup, it was probably thickened with flour.
Flour is used to make things stick when cooking. If it's breaded, it probably has flour. If it has added spices, the spices were probably mixed with flour. If it has ground meat, the meat was probably mixed with breadcrumbs to make it stay together.
Wheat is used as a filler in fake foods. If the food is made with tofu or fake meat, it probably has gluten. If it has bacon bits, its chock full of gluten.
If one of the ingredients is soy sauce, it probably has gluten. If one of the ingredients is malt, or malt syrup, or malt extract, or malt anything, it has gluten.
Sometimes restaurants will put pancake batter in scrambled eggs to make them fluffier.
Almost everything in grocery stores and restaurants has gluten in it.
Excluding gluten lets you know if gluten is making you sick.
Even better idea, just get tested. You can't do the test when you're gluten free, and if gluten makes you sick, going gluten free and then eating it for 1-3 months for the test will be miserable and perhaps dangerous.
I ate wheat with no issues for the first twenty odd years of my life. Then I developed psoriasis, an autoimmune disease. The psoriasis was probably unrelated, but I discovered that gluten was a trigger.
Whenever I fail to resist wheat (cake, pizza, etc), I end up with rashes all over my body and horrible bloating/gas. This subsides after a week or so of abstaining from gluten.
It's terribly inconvenient, and breakfast has gotten more expensive.

The gluten free fad is barely 5 years old.
(The small bit at the end where he tries to guess a reason can be ignored, since he's basing it on nothing.)
Maybe I misunderstood you and you were bringing that article to confirm what I said?
On the contrary, it's an extremely convenient way for fad-dieters to get the attention they crave.
