Have you ever replied to an email message by including the sender's email message? Did you ask for a license first?
I'm sorry, but you are guilty of copyright infringement, and may be liable for prosecution, as lovingly explained whenever we watch a prerecorded video.
Yes, it's true. Copyright is completely out of control in this country. It all started with "copyright reform" in 1976 and it's only gotten worse. Cautious publishers collect permission for EVERY image, photo, or quotation that might come from somewhere else. Never mind the notion of "fair use;" many publishers pretend it doesn't exist.
As a teacher, I rely heavily on "fair use" exemptions. Some classroom materials have a clear and simple licensing regime, but a lot of things are just "out there" without a clear process for licensing. It seriously interferes with education and even free speech when everything needs a license.
