A minor typo clarification in
@nextcloud's post (which I otherwise agree with). I'm not the sole author of any version of #AGPL. I invented the method that makes the Affero clause work¹, and I helped codraft #AGPLv3§13.
License drafting has many contributors; no one is the sole "author".
¹ I invented the approach of an additional requirement when modifying the software that the complete, Corresponding Source be made available to all who had access to the running software.
