Maybe we could not have guessed all the specifics, but it's obvious what happened. Somebody did not credit chipguide in the way you think they should credit chipguide. That is not and never will be a copyright violation. If Oscar even once in the video said or wrote that the images were from chipguide or a webpage shown was from chipguide, no violation has occurred. Fair use. Your demands are the equivalent of a realtor taking a photo of a house and having to credit the manufacturer of the paint color. They're garbage, and obnoxious.
