Seems to me that the greater issue here is safety.
Helicopters have always had a reputation, not always deserved, for poor safety. We are all victims and we will all lose something if this isn't stopped.
If con-men like these (and that is what they are) are making money at the expense of the safety of an unsuspecting public, then they need to be grounded asap. Seems to me it is certainly a criminal offence. Fraud, contrary to Health and Safety, Duty of Care, call it what you will.
They need ramp-checking. The CAA do this at the larger public events already. I suggest you contact the CAA and suggest where they might find it convenient to carry out a ramp check on these cowboy operators. The legislation is already in place as I understand it.
