Imagine 20 years from now you decide to run for political office. Do you want someone "ethically" going through all your old recorded conversations looking for statements that will be politically incorrect 20 years from now?
Not only you, but your kids. People have lost sponsorships and contracts because of things one of their parents said before the person in question was even born. Look at last year's incident where Eli Lilly pulled their NASCAR sponsorship of Conor Daly over something his father had said a decade before Conor existed. https://www.indystar.com/story/sports/motor/2018/08/24/eli-l...
Or intentionally don't watch what you say and stop giving this kind of system any power. If you run for office in 20 years planning to hide what you think now, or apologize for it, then you're in for a losing battle. Say what you think, admit when you're wrong, learn from your mistakes.
