Au contraire HC.
How is the big bad oil company Radio Operator meant to know when to call the helicopter crew with information? Make an appointment perhaps?
I have flown some offshore based tasks where the whole routing and payload was given over the radio at a suitable time. A normal change in payload or routing radio call should not be a hazardous flight safety event to any helicopter crew and neither should it be an excuse for a wrong deck landing.
Its how you manage to twist and blame the customer for every mistake which is "breathtaking". Ensuring that the aircraft lands at the correct destination is surely the Commander's responsibility.
