As someone who grew up with a (quite) younger sibling in the most disabling end of the spectrum, witnessing all the development from infancy to adulthood, I am very reluctant to recommend for/against any specific approach, because I think that what matters most is the people who actually practice it. So, I absolutely agree with the last sentence of your comment.

The negative aspects of ABA are not entirely in the past. I am not in a position to verify the information I will quote, but this is mentioned in the third of the linked articles:

Mandell says ABA needs to renounce that history — especially the early reliance on punishments like yelling, hitting, and most controversially electroshocks, which are still used in a notorious residential school in Massachusetts called the Judge Rotenberg Educational Center.

To be clear: I am not arguing with your experience here. Rather, I am pointing out how important is the kind of practice of whatever theory and what the focus of the practice actually is. It's really very difficult to find professionals who are actually both able and willing to care properly for autistic people. At least in the place I live.

Beyond that, I have to say that there are many things that now have positive effects on people's lives that weren't exactly positive in their original forms.
