It is a scientifically researched, peer-reviewed article that has some findings that were gathered by the highest scientific standards we can come up with. Whether people want to believe it or not, it's up to them. Whether it's enough to make a difference, it would take a lab to tell you the levels.
Walnut tree husks contain both the dye component, which is a phenol, and the juglone, which is an oil made up of quinones. If seeing the brown dye in plants that did uptake juglone was how it chemically worked, then all the leaves on a walnut tree would be brown, and they are not. Maybe someone here can give the chemistry at the molecular level, and explain the mechanism of action of juglone.
Here's the chemical description of juglone:
Here's a description of using husks and leaves if you want to dye things:
Here's how juglone kills lettuce seedlings at the root level:
