I understand where you are getting at, but there may be examples on YouTube where someone who uploads a video that they didn’t create but has got permission from the content owner to upload the video, but the content owner didn’t ask the uploader to provide a link etc. in the description box. How can I determine the copyright status of the video when it ain’t always clear…?
Fair Use is a bit of a mind field to me. For one video you may get ten people on one side arguing it’s Fair Use and ten people on the other side arguing it’s not Fair Use. How can I interpret it?
