>Now, ofcourse apple have positioned them selves as a privacy first company, so this is a big no no.

I don't think this is a "no no" based on Apple's privacy stance. The terms do say that they can send the recording in order to perform additional analysis and there's no user data, user ID info, or anything else that would give up a user's privacy included in what's sent over. Unless someone managed to recognize a specific voice in a recording, there's literally no way to tie a specific user to that recording because Apple anonymizes all of it on-device before it gets sent out.
