Have you (and I wonder the same about archive.org) considered making a Merkle tree of the data that gets archived? Since data (including photos and videos) are getting easier to fake, it may be nice to have a provable record that at least a certain version of the data existed at a certain time. It would be most useful in case of some sort of oppressive regime down the line that wants to edit history. You'd want to publish the tip somewhere that records the time, and a blockchain seems to make the most sense to me but maybe you don't like blockchains.
