Wow, that sounds like a joke to me. Why would it even matter if you had a conflict of interest, after all, the matter of the case is misconduct of Meta and Google and a conflict of interest on your side (if it even existred) shouldn't matter at all.
Also, we all knew they "deal" when we got into your token and supported your case.
If they really had a problem with you potentially ending up with "all that money", why not just propose going through a reputable law firm just for the sake of escrow?
