The Royal Commission is not yet over. The summary of findings on JWs is not the end of the story. The legal process is unfolding and the only open question is the extent to which jw organization in Australia will be legally mandated to change its policies and procedures on child sexual abuse.
(On the question of shunning those who leave, the Commission is well intended but has strayed beyond its legal brief. Expect a wet bus ticket on that issue)
Jw organization is perfectly entitled to respond, point-by-point from the perspective of their beliefs. Whether this is seen as arrogant or 'speaking their truth' is a matter of perspective. Although, even jw organization must know they do not emerge from this smelling sweet - and what a shameful issue to be in conflict with caesar over! So, as far as it can do so, jw organization will want to put a "decent" gloss on existing policies.
Ultimately, despite the huffing and puffing from both sides, I think the Royal Commission has made the organization significantly more aware of evidence-based responses to child sexual abuse. And some of the more egregious aspects of judicial committees (e.g., expecting the child to confront their alleged abuser) have already been stopped. And even before the Royal Commission, the organization loosened the hitehrto literal interpretation of the two-witness rule as applying to two different incidents involving the same alleged offender. But not nearly enough, I know. The point is, the organization at some level has realized its policies and procedures are out of step with accepted practice. This is also about 'saving face': Bringing about internal policy and procedure changes without making it overtly appear a forced outcome of any commission of inquiry.
Despite its tiresome posturing about 'following the Bible' and not being ruled by man, jw organization cannot help but be aware of how its policies and procedures look to the wider community i which they live. This is an organization acutely sensitive to how others, including existing members, perceive it.
