To say that it is not beneficial to certain breed does not mean it doesn't work.
Nothing in that study ever stated it was good for killing internal parasites.
It's a definite "maybe"

The results of this study indicate the DE has the potential to be an effective treatment to help control parasites and improve production of organically raised, free-range layer hens.
The other"benefits" they listed are meaningless since the birds were free ranged and not on a truly controlled diet.
They said the birds "ate more, weighed more, and laid more eggs, but that isn't proof the DE CAUSED those things.
If they ate more, it's only natural they would be heavier and lay more eggs even without DE
The only way to really test the effects of DE alone would be by feediing both groups the SAME amounts of feed, and not let them free range during the testing.
This study is used repeatedly to "prove DE kills internal parasites because it's the only study that remotely suggests it.
There are numerous scientific studies done by Veterinarians and universities who all concluded feeding it has NO effect on internal parasites.

However, BB hens treated with dietary DE had significantly lower Capillaria FEC, slightly lower Eimeria FEC, fewer birds infected with Heterakis, and significantly lower Heterakis worm burden than control BB hens
Note the "worms" they tested for are not that common in chickens, and don't cause much of a problem for them.
They counted on most people not knowing that, I guess

This parasite (Heterakis gallinae) is found in the ceca of chickens, turkeys and other birds.
This parasite apparently does not seriously affect the health of the bird

Capillaria (Capillary or Thread Worms)
There are several species of Capillaria that occur in poultry. Capillaria annulata and Capillaria contorta occur in the crop and esophagus. These may cause thickening and inflammation of the mucosa, and occasionally severe losses are sustained in turkeys and game birds.
Eimeria isn't a worm at all, but is a single celled Coccidia parasite that doesn't even lay eggs, so for them to say the FEC (Fecal EGG Count) was lower lessens their credibility

Tell me if i'm reading something wrong here. Basically, unless chickens are some kind of super bird strain that has increased parasite resistance and super high laying capacity, DE would work very well with your flock.
Since everyone concurs DE is mechanical in the way it kills, then logically it should perform identically no matter how "resistant" the host birds happen to be
