When Jack first started talking about Bluesky, in the very early phases it involved the blockchain. I remember suggesting that I thought the reason he liked the idea was that he could theoretically build a version of Twitter where no tweets could ever be deleted, and therefore there'd be no pressure on him to moderate or ban anyone. He wanted to not have the power.
People always thought I misunderstood Jack's motivations but it turns out I was right about him all along.
