This is pretty huge - Casey Newton’s is taking his newsletter off of Substack because of its ridiculous policies on hate speech.

In 2023, we added more than 70,000 free subscribers. While I would love to credit that growth exclusively to our journalism and analysis, I believe we have seen firsthand how quickly and aggressively tools like <substack’s newsletter promotion features> can grow a publication.

And if Substack can grow a publication like ours that quickly, it can grow other kinds of publications, too.
