Hey, Substack CTO here. We don't distribute Ghost's code at all and the only piece of code included is a client-side search library used by the third party theme. But that library is actually hotlinked and hosted on jsdelivr (via npm) with no modifications made to it what-so-ever. This includes the line at the top with the license link as Ghost originally built it
