I can't speak for Bonny, but I can speak for myself, as I have an autistic son. I am sure there are many wonderful therapists out there, and I have no doubt they can do amazing things. However, the big obstacle is the financial cost of such treatment. Insurance won't pay for treatment as autism is vewed as a psychological disorder, and being in the middle income range, we make too much money to qualify for state assistance, and not enough to pay for it out-of-pocket. So for us, we rely on our public school system and additional speech and OT as the school can provide. For many parents, we just can't afford a team of therapists.
In MJ's case I would invite you to go to Bonny's website about her little girl, to learn more about their situation.
