This story being rehashed (it is tacky claiming posters are up around the village, that sounds like "mob rule" - if they've followed the law then business is business) is an example of the media game Harry was trying to highlight.
The retail world has been shaken to bits over the last 5-10 years with covid and the big Internet shopping giants just taking over everything
(remember those halcyon days when Amazon was just "somewhere to buy some books from", and eBay somewhere to sell junk? Shein and Cider are slaying all the cutesy local clothes shops).
I assume the Middletons weren't able to keep up with their business model
but same rule applies to most retailers (look at how many big mainstream shops are struggling or going under, even with slick management boards and expertise).
(I'm not a fan or anything, but it just isn't fair).
The Press has (obviously) been sitting on this, and has reworked and put the negative story out as they want to "show the royal family who is boss".
Now the royal press office has to counter with something "in return" to sell papers.
The hacks have lost income from stalking and running negative stories about the Sussex couple now they turn on anyone else.
This may be why William didn't want Harry to detach - if the Press couldn't have one person to savage and bully, they would just go for the next available target to sell papers.
It's a dirty game, I hope the next generation can escape it.
