I don't like posting on this board for a number of reasons, but in this instance I'll break with my habit. I know the company of which you speak, and have known the "owner" for many years now. I am not familiar with the allegations of impropriety, as I have not been back to DAL recently to hear of them.
I don't know who is making allegations of impropriety, or how they came about, but I can tell you the "owner" is a top notch individual with solid ethical standards. I believe spreading these allegations without firsthand knowledge of the entire story, as well as commenting negatively on the interview prep service the company provides, is negligent.
Some folks in SWA management view interview prep negatively...they believe it interferes with them being able to judge the "real person" they are interviewing. I understand that point of view, but disagree with it. I think someone who goes the extra mile to do the prep is demonstrating a high level of desire to be hired by SWA, and for many, myself included, the prep (with a different company) helped put me more at ease during the interview and allowed me to better present the "real me". The prep is especially useful for military folks, who have no earthly idea how an airline operates, much less what "Dispatch" is.
That being said, if SWA management has a problem with a particular company, that is an issue between them, the prep company, and anyone on the "inside" who may have allegedly aided the prep company. Let them hash it out.
If you want to tell people the interview format is changing, fine, but don't spread rumors which may impugn someone's good name or bias future interviewees away from a service they may (or may not) deem valuable.
