It's because the game has not been legally distributed world wide (apart from the reviews) and these reviews were obligated not to release footage before release whether its a spoiler or not. They broke that, so Bethesda removed the video. I wouldn't call that "harsh" at all, its just the removal of a video, not legal action. Any released footage is to be from Bethesda themselves.
Anyway. I was smart about it, downloaded it
