This is how deep wealth is created: the moment something is beyond current law, drive a fully loaded train thru that loop hole, generate unregulated wealth, lawyer up, and write the regulations yourself. I'd say they might now exactly what they are doing.
No one has done anything, nor for that matter is it clear what current law you believe might be overturned; if someone had done something that was in violation of terms related to this matter and Facebook filed a motion, matter would be resolved by the courts. If you’re saying US courts would throw out contract law or laws preventing the laundering of stole property, likely need little more than two sentences and wealth to do so.
