As I read it, that post is not related to patent in question. That post
relates to using the hash of the document as a data locator/identifier,
while the patent relates to using the document hash as an _encryption
key_ for the data.
Freenet did (/does) both. It first hashes the plaintext to get an
encryption key, encrypts with that, then hashes the resulting cyphertext
to get an identifier for the document ("CHK").
