This is very much like when Musk briefly instated a policy that would ban all social media links because he was mad about Mastodon. That was obviously silly and quickly reversed. Now he's running it back, except he's managed to annoy some of his biggest supporters who make their money on Substack. Really weird stuff, because it's not like the new Substack thing is a genuine Twitter competitor.
