Feature not a bug imo.

Knowing your notes are "forever" forces you to think abt what you're putting out there. Freedom of speech is not freedom from consequence.

When people are more cognizant of what they broadcast out into the world, they tend to think twice and consider the consequences.

This in turn creates a more civil online society. Just like irl, once you say something out loud you can't undo it. This builds verifiable reputation and your actions follow your identity forever. Creates accountability and helps reduce toxicity. Brings back natural human interaction to the online world.
