I don’t think that interview was a good idea, it was really gossipy in parts, very self indulgent in others . And to talk so personally and publicly about your family like this, in such a negative manner, that’s a fatal blow.
I think there was a key vein of truth running through it, and critical points raised, although some nuances will be their interpretation of it, their truth, their perception and of course rhe royal family will have a different perception.
Ultimately though the royal family is more than an institution. This is still Harry’s father, brother, grandfather, grandmother. That’s who they were publicly attacking in front of the world. And it was clearly aimed at Charles and William specifically and everyone else, the rest of his family, was simply collateral damage.
For a couple who wanted to avoid media intrusion, to wish a private life, the nuclear level of escalation here is hard to comprehend.
