Neowin reports Microsoft accidentally removed many of its Windows related videos from YouTube. At first the massive removal of content was puzzling but it appears the video were taken down after copyright complaints. Microsoft discovered that users were posting stolen Window keys in the comment section of its videos, but instead of deleting the comments YouTube pulled the videos.
Here's the deal. Microsoft noticed that users were posting stolen Windows keys in the comment sections of legitimate videos and asked to have the comments removed. Instead, YouTube pulled the entire video, rather than deleting the comment that Microsoft requested.
Here is Microsoft's official comment on the issue:
While we are still investigating the recent YouTube takedown notices, it appears some of these videos were inadvertently targeted for removal because there were stolen product keys embedded in the comments section of the videos. Our intention was not to target legitimate YouTube content and we are sorry for the impact this has had. We have already taken steps to reinstate legitimate video content and are working towards a better solution to targeting stolen IP while respecting legitimate content.”
