You can have a face-to-face conversation with a friend, but how do you do that if you want to talk to a therapist? No therapist is gonna make an exemption and leave their phone in another room, not to mention, they literally write their notes into the computer system, instead of on paper.
And with lawyers? I just read about how Luigi Mangione’s conversation with his lawyer is being unlawfully recorded. How do you even have a conversation with your lawyer if you are in custody and they could just hide recoding devices all around the jail?
Sure, maybe they can’t use the evidence in court, but they could just leak an out-of-context audio clip to the press to win the “court of public opinion”.
It’s one of the thing where laws and audit can help a lot. Hospital (and lawyers) are supposed to secure their data. But nobody will care unless doctor loose their licence and hospital management get fired upon negligence with patient data.
