We’ve talked about this in IRC and IRL today but we never mentioned it in the forums.
A recent wave of takedowns notices affecting many of the Hitler “Downfall” parody videos has resulted in their removal from YouTube. (EDIT: These videos were blocked by YouTube’s Content ID system, not taken down via DMCA notices. For more on the difference between these two, see the EFF’s Guide to YouTube Removals.) The copyright claim is being filed on behalf of Constantin Films, the German production company that owns the rights to the 2004 film Der Untergang (Downfall), from which the clip originates.
