Nobody should ever use the DM as an example ever imho 
I agree with Starlight - the article seems stupid and irrelevant. There is nothing outlandish about ABA - it's common sense that intensive teaching and breaking things down into small steps, together with reinforcement will do far more for a child with a severe communication disorder and learning disability than a lets wait and see how they turn out approach.
As much as I hope ABA becomes more accepted, I strongly suspect it will never be easy to access as long as TEACCH is around - 1. cheaper, 2. no therapy involved - therefore no committed therapists required to put it in place.
I do think that it is actually not easy to find great therapists (even though we've had some really talented ones) - it's so important to have the right people.
