At the heart of this is a very greedy racket:- court reporters who 'own' the copyright to every word spoken by anyone in court that they transcribe to a transcript that they do not own the source to (judges/witnesses/lawyers/defendants in truth own it) They then milk huge fees for these transcripts and limit use/access/derivative works with huge fees. An AI verbatim transcriber would up end them, so that will be prevented, as will anything that shakes the tree.
