My guess is the sheer amount of data that archive.org has, which means:

- even higher costs associated with seeding archives (egress traffic, storage iops capacity required etc)

- chances of finding a 3rd-party seed for arbitrary file would be pretty slim, which means seeding on your own most of the time, which would make this hardly any better than offering files over HTTP only.

Anna's Archive, after all, is only an index.
