Personally, I find it uncredible because of how disingenuous it is.
Everyone collectively shut up about Epstein from 2021-2024, and nobody actually cares about anyone presently implicated in being an Epstein client other than the possibility that Trump is.
Nobody has really done anything about Bill Clinton, Bill Gates, Stephen Hawking, Prince Andrew, or anyone else undeniably implicated. They're not even reviled to be pariahs, Clinton was a speaker at some of Kamala's rallies and endorsed her, and many still take Gates's climate activism super seriously.
The idea that "we need the files to punish the guilty!" is Dimensional Merge CWCville-tier delusion, that anyone can or will do anything, with the lack of any such actions despite names and evidence being present for at least 6 years now.
Nobody actually gives a shit about Epstein, they just want something to go after Trump by tying him to something that can't be proven or disproven, despite that the entire Epstein case is only in the public conscious because of Trump's DOJ prosecuting him in 2019. The moral outrage is entirely fake, the most credibly damning thing against Trump in there so far is that Epstein might have sex-trafficked a 23-year old to Trump, but nobody cares because it wasn't a child, despite the infidelity of Trump and participation in any sex trafficking being abhorrent.
It's all one big theater kid act, that has conned the general public into being audience participants.
