If these companies were breaking laws against big people (facilitating investment fraud, payment processing for terrorists) nobody would consider these methods of deflection for a second - it's only because the laws are being broken to hurt small people that the concept of aiding and abetting or acting as a willing accomplice is considered not relevant. (Human rights are common law.)
