I don’t think we can begin to understand how personal this feels for Harry, the growing up in a goldfish bowl, the blame he feels towards the press over Diana.
It is also extremely sad that in very many of these enquiries (including arguably bigger wrongdoing/cover ups such as windrush, grenfell cladding or infected blood products scandals for example) that organisation and individuals come to the stand and claim not to have known things, but it’s rare for any individual to take responsibility for the things they did or knew about or turned a blind eye to. I don’t know how victims and families really feel when the end result is a pithy apology from a company representative or the current government, and a bit of compensation.
otoh Harry himself still likes the privilege and renown that press coverage provides, he still believes that his status by birth qualifies him for a princely life without having to earn it, and doesn’t seem to want a normal, obscure life. He is happy to spill secrets on other people for cash and has kept quiet when his fans have behaved terribly and presumably unlawfully towards Catherine, particularly in the online sphere. Going after the tabloids is rather closing the door after the horse has bolted when the internet is the Wild West.
I don’t expect him to be a dragon slayer to solve all the worlds problems, he obviously has a heart for protecting particularly children from online harm, and the environment. But it’s the idea that just by turning up and being Prince Harry is some great gift to the masses, then driving off in a big SUV to where the private jet is waiting to take him back to his mansion or polo field would be quite alienating to much of the public I would think.
