I used to be a fan of Zitron after listening to an old podcast of his, and also subscribing to his newsletter.
Something weird happened after Taylor Lorenz guested on his show; a week later I received a welcome email to Taylor's own newsletter. This was especially strange because I definitely hadn't signed up to hers, and use individual masked emails in Fastmail per different service so I was sure that this was the email address originally used for Ed's newsletter. I tried to contact Ed to no avail, and since that day I never could shake the feeling that he just gave Lorenz his subscriber list. I can't prove it for certain, but there was definitely something "off".
