My dc (17 years of ABA and counting, across home programmes, and 3 schools) has never had any abusive behaviour modifications, or any other type of abuse.
ABA has helped with:
stopping socially unacceptable behaviours ( NOT harmless hand flaps and stims, but things like masturbating, or poo smearing)
recognising socially acceptable behaviours are needed and essential in some situations. Eg, my dc adores going to the theatre. She has had to learn how to behave in a theatre if she wants to see a show. Yes, there are relaxed performances, but not often enough, and often not at convenient times, so if she wants to go to a show (and she really does want to go to shows), then appropriate behaviour is necessary. No aversive methods used, just lots of patience, explaining, and building up her ability and understanding slowly over time.
teaching her how to interact with her siblings, and how to play.
teaching her how to read and write, how to dress herself, and how to manage a lot of her personal care.
teaching her how to cook simple meals, how to organise herself, and how to help herself too. She often now reminds me about the things she wants or needs for a day out, will discuss if she wants certain sensory objects with her, whether she needs eg ear defenders, can make choices about how to spend her time.
all of this is possible due to the individual curriculum she has had, focussing on working on the next best step for her, in a way that she can engage with, at a pace she can tolerate. None of it has been abusive in any way, and none of it has been designed to stop her being herself, but to help her get what she wants out of her life.
she currently has work experience in a small office, where she can answer the phone, take messages, and help with filing. She has had great success volunteering at a pre-school, helping with early phonics work and singing groups.
she is currently undertaking a course of therapy (general therapy, via NHS referral) which she has chosen to do to try to help with a phobia she has. Is working on that, and ‘changing who she is’ more acceptable because it isn’t being delivered via ABA?
