It's a common test to ensure you're truly comfortable with your decisions and actions: If a major newspaper would describe your actions or quote you directly on their front page tomorrow, would you still stand behind those words and actions?

The "test" is much older than Stripe but we often use it as a shorthand to ask ourselves whether we truly think a certain course of action is the right one.

It is a great principle. Great benefit, easy to upkeep

I have no idea why most companies don't install this principle since the beginning.

I basically assume every email and slack message would be public at some point.

It is a bit extreme but it doesn't require that much effort to maintain such principle.
