so, let's start with what ResetEra gets wrong because it seems like there's a post going around, and the person who made that post is unfamiliar with jailbreaking
the post said that people were exploiting a license loophole by "grabbing the indefinite license file for the thing off of an exploitable PS4", This is absolutely impossible, because:
1- you cannot buy games on a jailbroken console since you cannot access psn store, so you must update to the latest firmware to be able to buy games
2- once updated and accessed the store, you cannot extract the RIF (licenses) cause there is no jailbreak on the latest firmware and hacked consoles cannot buy games, current jailbreak is PS5 fw 12.00 and lower, PS4 fw 13.00 and lower
3- in an alternate universe where PS5 and PS4 is jailbroken on latest firmware and can access psn store and buy games, it would be pointless to buy then refund, cause jailbreak already has free games that you can grab.
Now, here's a real analysis from developer egycnq who worked on PS5 Jailbreak 12.00 and has long expertise in hacking https://xcancel.com/egycnq/status/2049150845124485340#m the 30 days check was added to the license file, you don't get a "permanent license" after 14 days, the check is hardcoded it seems. unless they're somehow remotely changing your license file hex values from their server... odd and unlikely but who knows.
Now here's the reason why Sony might've added this check, there are some exploits in multiple games, the first one is called Mast1c0re, the second one is Lua exploit and the most recent one is Luac0re (a mix of the other two), those we call them Userland, aka Entry Points, so by buying an exploitable game and going offline, you guarantee an entry point to a future jailbreak BUT... this changes now, since you have to check your license
and you must UPDATE your console to the latest firmware to do that, meaning, no jailbreak for you.
those are save file exploits, Sony cannot patch them it seems, since they're in the games, not firmware side, unless they patch the saves on those games then re-release them, imagine. it's so so unlikely. so 30 days check is the feasible way.
TL;DR it ain't a license loophole prevention.
hopefully this helped clear the confusion
