Wow trying to keep up with it all is head spinning
The notion Harry and Meghan 'having to use Ikea furniture' is ridiculous. Harry had a trust fund of several million pounds and Meghan had earned significant amounts from acting. I'd also ask how did they go from not being able to afford to furnish 2/3 bedroom Nottingham Cottage but could furnish - to what ever extent fell to them- the much bigger Frogmore Cottage.
The Queen will not have, for one second, begged Meghan about anything. While she may have advised Harry and Meghan that she shouldn't wear the Spencer tiara it will not have gone beyond a firm bit of advice (which the family will have known was an order wrapped in advice). Other than the Spencer tiara the Lovers Knott is the only other tiara the late Diana wore and it is crown property - the Queen wouldn't had to have begged Meghan not to wear it she simply won't have offered it / allowed her to.
William vetoing wedding venues - more likely he was just giving Harry a reality check. St Pauls was never going to be an option, WA was really OTT for Harry's status and I think since Edward's wedding Windsor has become the default. It seems to me Harry is taking everything William ever said as him dictating/laying down the rules etc. But surely as brothers (in better times) they will have had mere conversations where William will have offered advice and his own thoughts as friendly advice. Anyone being a little negative and suggesting against H&M's plans seems to be made out to being against them and horrible.
Likewise William saying whatever he said about Harry's beard for his wedding is 100% spot on IMO, military rules at the time said no beards so William is only being proper. I doubt it was a huge issue it is now being made in to more of a "you'll have to shave because its the rules, even Granny will say that".
The more we hear and read the more it becomes clear that the biggest issue is Harry and Meghan not getting on - for whatever reason - with William and Catherine. That seemed to spur Harry into having all these "inferior" feelings - the third wheel in the relationship, the smaller royal residence etc.
It is clear IMO that Harry is not very mentally robust at the moment and this book does give me the same feeling as when we watched Britney Spears have a breakdown back in the 00s. It feels a bit exploitative, like everyone is getting what they want from it - the book publisher, the ghost writer, the media, Netflix, but is Harry getting what we wants from it? Really? How will he feel in a few years, especially when he realises that the book is why what left of his reputation and respect for him has gone and why he will now never truly be able to reconcile with his family.
There are a number of perfectly valid points Harry raises in the book it seems but, as always seems to be the way with Harry and Meghan, the "smaller" indulgent points, the unnecessary points that only seem to cause upset to others overshadow any of them.
