I can certainly empathize with how making a personal conversation public might upset someone, but I hardly see how this comes close to qualifying as defamation or false light. Federal (US) law requires that one participant in the conversation consent to recording and we can assume Ivan did. The conversation was also edited to avoid revealing any personal information including something as small as Aponic's first name. It's an international call. There were hardly any damages. What legal precedent is there?

And what makes the sharing of this conversation significantly different than sharing private logs or private messages?
