The concern is not people selling it -- no licence stops that, and the AGPL does not try to -- but someone building a proprietary product on it and giving nothing back. Plain GPL would leave the obvious hole open: lectio-web is a network service, and hosting is not distribution, so a modified lectio-web could be run as a paid subscription API without ever publishing a line. AGPL section 13 closes exactly that. LICENSE is the verbatim FSF text. README carries the standard notice. Section 13 requires a modified network-reachable version to PROMINENTLY offer its source to the users interacting with it, so the offer ships with the code rather than living only in a file nobody fetches: - GET /source plain text, no template or config dependency, so it answers even when something else is broken - page footers every full page (fragments render inside one) - JSON envelope "source" / "license" - iCal header X-LECTIO-SOURCE / X-LECTIO-LICENSE The feed fields are not redundant: an /api/calendar.json consumer or an .ics subscriber never loads a page, so the footer alone would miss them. config.SourceURL is the single source of truth, and says in its comment that a fork running as a service must repoint it -- an offer that leads to someone else's code is not an offer. Tests pin all of it. This is a licence obligation, not a feature, so it should fail loudly if a later change drops it. 2026-07-27T19:25:43Z Lukasz Kasprzak lukas@labunix.xyz 2026-07-27T19:25:43Z urn:sha1:45e0b7652552867f7f99ffe22c968641510d5143
