Some possible explanations:

a) There is zero legal merit. As an outside observer, I don't know one way or another. I presume you don't either. (Remember the law does not always track your intuition.)

b) Even if there is some theoretical legal merit, the independent investigation results (if what we're told is the entirety of the conclusions) may make it an uphill battle to pursue the claim.

c) There is actual legal merit but the potential plaintiff is choosing not to pursue the matter.

d) There is actual legit merit and the attorneys are in settlement talks right now.

e) There is actual legal merit and a lawsuit will be filed before the statute of limitations expire.

Who knows?
