Watching the disney mashup I don’t agree with how copyright works, or was working. The 14 year rule honestly doesn’t make any sense. Its an insult to one’s art or work when you claim that “after 14 years this work is up for grabs!”. My opinion is that once you publish your work, it should never be able to be stolen, even after you die.
Although I disagree with the copyright rules. I don’t think that everything should be labeled “copyright infringement”. A person playing a song on youtube behind their video doesn’t mean they want to “steal” the song. Deeming acts “copyright” should go through an ethics committee before accusing an innocent person for playing a song
