I bought a video (or thought I did) where the seller made up a song and performed it on camera. Then he posted it to YouTube, which wasn't part of the deal. That made it useless to me, as I had planned on editing it and adding more content. Plus, of course, I want it on my channel, not his.
Now there's another video seller (oldbittygrandma) who insists on superimposing her credits and copyright notice over the beginning and end. Plus she watermarks the video in the middle. Plus she will only post it to her YouTube channel.
These alterations would make it useless to me. Would you buy this?
