A lot of people who believe in FC and it's variants believe that there's a big conspiracy to silence the voices of their children. They don't think it's relevant that there was a facilitator who was just "supporting his arm" or "providing contact" or something of the sort. So they are unlikely to do this; they want to promote a notion that the child is producing the text, not the facilitator.
