YES, I'm reading his book now and I recognise things in his life that are similar to things in mine (on a less public scale of course). I posted about it in another thread (copy/pasting it here):

Harry may not have suffered as much in the way of physical abuse but he has suffered a LOT in terms of emotional abuse and neglect. And these have clearly affected him deeply psychologically. EA and EN are just not talked about enough in general, they are glossed over but can be extremely cruel and destructive to a growing child, sometimes even more so than physical because it creates deeper psychological effects that takes years/decades to unravel.
Coldness, lack of hugs, humiliation, being the scapegoat, being made fun of in public, gaslighting, hypercriticism, being ignored, being over-controlled, being shouted at - in private and in front of people.... all these things can really undermine and destroy a child.
Harry has definitely suffered many of these, especially the humiliation (in the media, on a public scale eg while at school etc), and coldness in terms of his family, and being thought of as second best/spare option. Leaked stories in the paper about his apparent "thickness", etc all these things publicly defined him in a way that he never allowed.
I understand the anger he must feel because I went through similar things (not in the media of course). I grew up with an overcontrolling, hypercritical mother who would loudly criticise me to anyone who would listen and I still feel extreme anger that she defined me to others that made them think less of me rather than allow them to get to know me. It left me with a lot of issues, such as selective mutism, panic, feeling of emptiness and other things that still affect every aspect of my life.
He's clearly been through a lot of therapy and it shows. He's seeing things clearly now and speaking up about it. And I actually applaud him for it. It might sound like he's being childish but I think it affected his development and only now he's becoming to recover. Sometimes you need to call things out in the open, and if it means you burn bridges you burn bridges.
You never know, it might make the RF more self-reflective about their own behaviour as a family.
