If there was a potential sale, it is unprecedented that something didn't leak yet. I worked at a top 10 Global Law Firm for 5+ years as an IT Manager. Everyone knew the buzz when a big case was going on. The business does everything they can to prevent it with ethical walls in the document management system and password protected documents, but people talk. There are most definitely 25-50 associates and partners working this case with Suss not to mention the countless IT, AV, Library and Receptionist staff which are involved in this every step of the way.
If Amazon was in the picture, this would have leaked by someone involved along the way.
