By most measures, Forever Wars <\/em>should have been a Substack success story. The newsletter, which documents the war on terror, began last year after Substack cut a deal with a seasoned reporter to write on the platform, build an audience, and \u2014 if everything went well \u2014 launch a reader-supported venture that made the switch from newsroom to newsletter worth the gamble. Substack\u2019s usual promise applied: if a writer wants to leave, they can, and it will be easy to do. And, in late July, a day after the expiration of a year-long deal, that\u2019s what Spencer Ackerman did, moving Forever Wars<\/em> to the newsletter platform Ghost as seamlessly as possible.<\/p>\n
