Are you against the cure in principle or because of its impossibility? As, properly understood, I'm all for cures and these people might be taking a more moderate interpretation for all I know.
To be fair, the program does not seem particularly different from what books on autism would recommend to help any child with autism, be it severe or mild. Granted, those books don't mention the word cure... I guess it depends upon what you wish to cure. They obviously can't cure 'Autism' as that's supposedly a neurological disorder, but it might be possible to 'cure' extreme communication failure, quite simply by taking the correct approach when it comes to interacting with the child.
Also, given that autism is such a misunderstood concept scientifically, it is perfectly possible someone out side the medical community might have ideas which the medical community has yet to adopt. That happens often in the history of medicine, granted I very much doubt it is happening here but there is still a possibility.
Don't know if I'll be busy that day but if I do go I'm afraid I'd have to give them a chance first.
