This is a fantastic feature. It isn't so much for the company to prevent it but a way for the guy being pressured to share the recording to say "I'm sorry, I can't. They embed details in it that if they were leaked would ruin me." i.e. technology that allows you to say no to things is great.

The most extreme example is a secret that if I shared with you, I'd die painfully. You can't threaten me with death or torture because that's what's going to happen to me if I share it with you.
