That was Brian Stetzer, who was threatened by Wood for disclosure. A lot of the leftie sources are saying it was probably just "nuisance value", so who knows.
On the other hand, Woods law firm blew up over fee-splitting on a big case that was settled about that time, so if it was that case, it may have been large.
I didnt look at the timing of all their allegations as I just skimmed the lawsuit. Keep in mind they were also likely working on the Elon Musk suit...which Wood Lost.
