Strong copyleft

GNU General Public License v2.0

Classic strong copyleft still widely used; distributed derivatives generally must remain under GPL-compatible terms.

Compared to common options: Stronger than MIT/Apache/LGPL for distributed derivatives; AGPL adds network-use source obligations; GPL-3.0 updates patents/DRM themes.

Generally allows

  • Commercial use
  • Modification
  • Distribution
  • Private use

Typically requires

  • Disclose source when you distribute the software
  • Include license and copyright notices
  • Keep distributed derivatives under GPL-compatible terms

Watch-outs

  • Distributing proprietary closed derivatives of GPL-covered works
  • Holding authors liable

How teams usually use it

  1. Confirm whether the project is GPL-2.0-only or or-later — it changes upgrade and compatibility options.
  2. SaaS-only use without distribution may not trigger the same release duties as AGPL.
  3. Map dependency license compatibility before combining with proprietary or incompatible code.

Orientation only — not legal advice. Always verify the repository LICENSE file, notices, and dependency terms, and obtain counsel for commercial distribution decisions.
