NGOHQ received a response from Microsoft regarding the Windows 8 DMCA takedown notices that numerous tech websites received lately.
"Microsoft is committed to ensuring that copyright is respected online. To protect our intellectual property, Microsoft's anti-piracy programs target links to infringing copies of our software; we do not target commentary. We take reports of inaccurate DMCA notices seriously, and will investigate disputed notices upon receipt. If the sites do not contain links to infringing copies of our software, we will contact Google about reinstating the search results." said Mark Lamb, Senior PR Manager.
Sounds like a standard PR message with lots of words but little meaning. I can confirm that there's been some strange DMCA takedown behaviour from Microsoft lately as I myself received a message from Google last week that Microsoft submitted a DMCA takedown order regarding an article on DV Hardware that described the new Metro user interface in less favorable terms.
The weird thing about it is that the URL they requested a DMCA takedown for didn't use our current link structure and contained unnecessary variables. I suspect these takedown notices are the result of a bot crawling the web rather than a team searching for "bad publicity".
