Shameful and unethical.
Per the community site: "Any documents, papers, text, data, or other information posted by NetApp on the Site is and shall remain the sole property of NetApp and may not be copied, modified, moved, translated, adapted, distributed or displayed without NetApp’s prior written permission." (Ironic I just did that, but you did seem to violate these terms by re-printing content you found on their site).
Also in the Code of Conduct on their site: "You will not disclose any third party confidential information." This information was clearly meant to be confidential, and you knew that when you reported on it (and admitted as much).
By publishing/reporting this information you have knowingly impaired a corporation's ability to conduct business as it sees fit. This isn't the same as someone leaking government documents as the government is a public entity. Netapp is a private firm, and someone seems to have made an honest mistake that you have exploited to promote some Anti-Netapp agenda. I believe an example needs to be made of you guys, this is NOT the kind of technical information I expect to read from an industry site.
If you want to work for Gawker go do so.
