So, I think a real issue is that it's not made clear how this archive exists. In Citizenfour, it was made clear that Snowden specifically gave the documents to journalists for the purposes of responsible disclosure and reporting. There was the suggestion of publishing the archive in public with all data, but that was shot down as it was too risky in Snowden's eyes. So the archive is mostly a huge collection of documents that have to undergo editing for opsec reasons, so as to not endanger actual people or reveal enough that it might go from "journalism" to "espionage" that warrants a greater release. I don't believe the full archive was ever public. Instead, it was privately held and being maintained by people for research and publication. The Intercept winding this down signifies they no longer care to sift through or maintain the documents. That means that the editing part is gone, and they won't devote further resources internally to it. The decision to host the documents isn't the issue -- moreso the maintenance, reporting, and sourcing.
