What I meant, if you are holding and sharing an entire file of some really sensitive content and depend on networking technologies known or assumed to have flaws which can expose your IP address you have relinquished ability to deny it.
Whereas is this content has been published, using something like Freenet, so no single user of the content distribution system has more than a fragment of that content and what they each have is not only encrypted (and you don't have the key) but its bit interleaved and your software has no idea what part(s) of the content you hold nor where those other parts reside (for that your software must possess the file's "treasure map" which can be closely held). This offers good plausible deniability.
