It's honestly a really big setback.
The money factor is why this happened, why they pursued such blatantly hammed up lawsuits, taking almost a year in one case to even organize the story enough to file it, and Wade/Safechuck really needed loads more people filing, hoping the effect would be massive and terrifying for the estate, who would seemingly in the end most likely prefer to throw money at these people and get their silence than endure all of them running about to the tabloids. That hasn't happened.
So with both lawsuits already requiring amendments, and one almost outright dismissed, it's making it more unlikely any other people will ever come forwards to join him. Not only would they have to deal with trying to make their own story seem reasonable (if they claim Wade released them from their mental prison then that happened 2 years ago already, the estate is nearing 6 years old and almost every other child involved in MJ's life has already been on the record since his death in some way showing they side with him, including Spence's family, so they have to navigate all those bypasses into explaining why it's taken them so long to realize what happened), but they'd know they'd get almost certainly rejected right away so what would be the point, besides hoping for scraps from Wade or the talkshow circuit.
I'm only curious what the amendments will be - Wade has to prove people around MJ knew and were in control of him (will he find that info in all the 2005 court docs), Safechuck has to change pretty much his story from 2005 on. I'm wondering if they'll change it to claim even more dramatic and grotesque things they've suddenly remembered, just to get the tabloids reporting on it again. Any changes are good for us though.
