I'm not clear on what you mean. General usage of the word "release" necessitates prior confinement. Dumping a bunch of data on an open web server is not confining said data, it is making it public. Even if the data was previously confined -- by, say, company policy or copyright or whatever -- as soon as it is uploaded to the public-facing web server without protections it is released from confinement.
