It’s also because Apple’s permissions are hilariously monolithic. A lot of their permissions are set up as an all-or-nothing event, instead of allowing granular control. Full disc access is a great example, where a user should be able to grant access to specific folders and files on an as-needed basis. But that’s not the default behavior. The default behavior is to just go “hey do you wanna give this app access to everything?
It’s because you only need to take an oath if you’re testifying. And arguing isn’t testifying. Lawyers are already bound by ethics standards for things like lying. For instance, if a lawyer knows you killed someone, they can’t openly say you didn’t.
They can argue that the evidence is lacking. They can argue that the prosecution hasn’t done enough to prove your guilt. They can find gaps in the prosecution’s case and start poking holes to provide reasonable doubt. But they can’t put a witness on the stand who they know is going to lie in your defense. And that includes themselves. Also, no lawyer would want to take the stand, because then the opposing lawyer would have a chance to cross-examine them directly while they’re under oath, and likely have them testify against their own client. It would be a very big can of worms.
Apps can’t add permissions via an update. If an app adds a new feature with an update that requires a new permission, the user will be prompted the first time the app tries to use that new feature.
