Drone.io is no longer Open Source (source available, non-commercial)

Drone.io is a CI system with a minimal and very fast interface, especially in comparison to the monster that GitLab is.

I'd rather have AGPL licensed code or an open-core model with proprietary enterprise features (e.g. LDAP/Active Directory auth), but I completely understand that making money from open source software is hard (see similar changes with Redis/MongoDB).
