Maybe I’m out of touch, but doesn’t a $1.4b dollar settlement for this seem rather… large?
Alongside the class action, Jones was iirc also facing several separate lawsuits, so what you're seeing here is multiple lost lawsuits (I think he lost 4?) adding up.
The bankruptcy also doesn't wipe the slate clean for Jones afaiu, because he specifically was found to be malicious in his behavior. Court debts aren't wiped in that situation. He's still on the hook for that.
