Open source or free software is a stance.

If you say Open Source it implies that the choice of a copyleft license is a strategy to improve your return of code, but the default is “just be open”. The goal is to get other people to support you.

If you say Free Software it implies that the choice of a lax license is a strategy to improve your spread, but the default is copyleft. The goal is Freedom. It sounds easy nowadays, since there is so much Free Software that if you have some free time you don’t feel the restrictions from proprietary software.

If you want to feel the restrictions from proprietary software again, try changing the layout of gmail and keeping it in working state for 5 years.
