A one-off mistake or a sign of copyright battles to come over Mickey Mouse?
So basically Google/YouTube needs to remove the items from its database that are no longer copywritten.
Basically it doesn't matter. Google sucks the cocks of any Corp making a claim regardless of how valid it is. I had fucking ads put on an unlisted video of a scene analysis I did for a movie class, entirely voiced over by me. Educational and transformative. Textbook fair use. YouTube said "nah if you contest it again you get a strike."
If the undertale yellow situation has shown anything, it's that YouTube is worthless and we should dump it
I’m waiting for someone to make a “Steamboat Willie remix” and then content claim all future audio tracks.
