No, Nannee His extended family supported him when his parents divorced and his mother died, and he stated publicly that they were there for him when he needed them. They helped him get counselling to counter the stress he suffered. Then he married and wished to break away and live his own life, independently - as most young men wish to do.
He had a personal fortune of, I think, £40 million pounds, left to him by his mother, and his wife is wealthy. Despite this, he says he is disappointed that his father is not bankrolling him. Most people would not think that independently living your own life involves expecting to live it using your father's money, while simultaneously complaining about how he treats you.
"All the fuss" is in the press and the minds of the public, because it was agreed between Harry and his family that he wanted to leave the Royal Family, and that was done, as he wished . He then used a prime-time TV show to rubbish his entire family. The strong criticism came from HIM. His family has said very little and certainly no "strong calling out" They haven't held an entire prime-time show to counteract his (and his wife's) version. Please supply a source for this calling-out - if you have found a reliable one.
