Once in awhile, blinds accidentally hit a bullseye, but by the time they do, it's what most suspected from enough decent leaks. I would view them with caution - they print anything they like.
The only story that has veracity is the basic one: a narcissistic, grasping, aiming for global fame but unable to get it on her own merits and running out of time at 36, snags one of the most high-profile boys on the planet, who has numerous emotional problems, is notoriously immature and dim, and gets a title, an HRH, a free home, a million dollar wardrobe, a $30 million wedding, a rich father-in-law, and the much longed for global fame and attention.
Instead of a shrewd appraisal of the benefits of the long game, the narc, unable to accept "second place" despite its massive perks and advantages, goes into a frenzy of competition with the future King and Queen (both sets, actually), but especially focuses her envious hatred on the One Day To Be Queen, better-looking sister in law with the long, glossy locks the narc is obsessed with, and sets out to make as much trouble as possible for her and for the family from whom she got so much, but that the narc feels still isn't enough.
By the time she's been married six months and is safely pregnant with her anchor baby and negotiating tool, the narc makes it clear that she's planning to bail, as well as revealing a few other nasty character traits. Underneath it all, no matter what they said publicly, the family were likely relieved to find out that the endlessly whingeing, bitchy diva wanted out, because they'd got the narc's number quickly and realised she was more trouble than she was worth. The question was how to do it with as little damage to all concerned as possible.
But in this, as well, the narc refused to listen to reason and she so often does, made faulty assumptions about being able to bully the Queen into giving her what she wanted by publishing her "manifesto" before negotiations were complete. She found out that the Queen wasn't that easily bullied, and herself and the Not As Rich As She Thought hubby more or less booted off the island without their HRHs and SussexRoyal, and in not given the half-in, half-out, cherry-picking role the narc thought she would get automatically, just because she said so.
The rest is history: Charles' money spent on all that trademarking and web site development down the crapper, no HRH use, and a pandemic that keeps the narc penned in during a crucial period when she needed to be out there taking advantage of interest that is already waning. She loses the first battle in a lawsuit that will be ultimately damaging even if she wins it because of what will come out as it proceeds. Her lawyers don't even bother trying to make better arguments for the charges the court ordered dropped, but submits the amended complaint without them, and thus focuses the case on an issue that will bring the PEOPLE Magazine article into play in a way the narc and her "friends" won't like.
The narc continues from afar to try to damage the family, who now know that they can never welcome back their prodigal son whilst he is still attached to the nasty spiteful bitch he married. William and Kate would probably, rightfully, refuse ever to be in a room with the narc again barring Philip's and HM's funerals. The narc helpfully burned all her husband's bridges for hubby. That includes the TATLER piece, which by now everyone knows has the narc's fingerprints on it at a third remove.
The narc will continue to annoy them for the rest of her life. Serves them right for not having the balls to tell Harry to head off to America with her right away, instead of giving her the platform she wanted, and giving her enough status to be a thorn in their sides for another 30 years.
The rest of the story, the leaks and rumours (true or not) are just sidebars to the fundamental family tragedy the Windsors brought on themselves through a long cultivated risk-averse policy.
