While I don't think what Carl did qualifies as fair use, I also think it's patently ridiculous that the woman suing him is seeking $150,000 in damages for it. In what way has her reputation been damaged to the point where $150,000 could be deemed reasonable compensation? All he did was repost a section of one of her videos to his YouTube channel with a mildly disrespectful title. Is that really worth getting into an expensive legal quagmire over? This whole situation makes them both pathetic, frankly. The average 10 year old has more perspective and self-awareness than this.
