Lately we heard a lot of the "YouTube vs Gamers" controversy, with hundreds of copyright claims from several known or unknown companies blocking videos containing gameplay and game music and threatening the earnings of many YouTubers, but the new rules can give a headache to corporations as well, as it happened to Microsoft.

Upon releasing the Call of Duty: Ghosts Season Pass Trailer two days ago on the official Xbox Canada YouTube channel Microsoft saw it blocked by Activision on copyright grounds, as you can see from the picture below.

Of course Microsoft isn't your average YouTuber, and has a little more leverage than others, so the claim was subsequently removed and the video reinstated (probably after an angry call or two), but not before a couple commenters and quite a few viewers noticed the hoopla and took screenshots.

If even Microsoft can be affected, albeit temporarily, by the new rules, we can only imagine what kind of grief is being thrown at normal YouTubers with a lot less leverage on publishers.
