What is the open-source software movement?

The open-source software movement is a social initiative advocating for licenses that allow anyone to view, modify, and distribute software source code. Emerging from early computing traditions of academic sharing, it promotes voluntary collaboration and transparency over proprietary development models. Today, open-source software forms the foundational backbone of global digital infrastructure across industries.
