You have now completely lost me? Calling it "junk science" is pretty strong, and I think inappropriate. It is well documented how earthworms affect soils. In most cases it is a positive affect, however in some cases it apparently can have a negative affect. I am confused at why you cannot see how exotic introduction of earthworms into an ecosystem can have a dramatic effect on the ecological composition and structure of that system. If you think the information and findings are incorrect, then you need to read the publications and formulate a logical case against them by either presenting a discussion of research that contradicts their findings and/or do your own research.
