The difference here is that Brady and Bundchen not only received payment in equity as brand ambassadors they also invested into a stake of FTX. The conflict of interest is probably more actionable but the official role could make him subject to being an insider. Obviously there is a lot of negligence to go around here but if we swapped Ja Rule for Brady and FTX for Fyre Festevial (and Bahamas for Bermuda) we can see that some lawyers have gainful employment for a while.
