As for restaining or incomprehensibly bossing, people do this with neurotypical children all the time. I fail to see why they'd behave any differently with autistic children.

They may, for instance, learn that the meaning and effect of their 'bossing' behavior is different on the child in question and realise "Hey, me keeping up the incomprehensible bossing and restraining despite knowing the (significantly negative) consequences in this case would mean I'm a total asshat, I'm going to stop!" So, crudely speaking the reason you claim to fail to see is that not all people are one of ignorant, incompetent or malicious. I can only assume that you are intending to deny the premises (regarding the degree of negative effect those behaviors can have.)
