The article says, "the group is demanding that Apple pay an undisclosed ransom for the images/schematics they obtained via the supplier by May 1 [...] Until then, the hackers will continue to post new files every day, REvil said on its blog."
The target is only Apple itself, the random group does not accept third-party payment and will make all information public if it's not payed. So I don't think the group wants to sell the information to accessory manufacturers or Apple news sites.
That wouldn't be a viable business model for the ransom group; Any accessory manufacturer or news site would likely get in a legal entanglement for buying trade secrets.
Because they're so ethical? If a third party wanted to pay them $50M or even remotely close to that, they'd accept in 0 seconds.
