Short explanations of free software

Explaining the idea of free software can be difficult. Let's list our favorite short explanations here, and pick the ones we like best.

• Free software is software that you're free to use however you want, understand, modify, and redistribute. These freedoms create conditions such that *we* control the software we use, rather than big companies using it to control *us*. Software freedom also provides a basis for collaboration (since everyone is free to build on each others work) which sometimes happens at an incredible scale. Working together, free software developers have built a entire operating system (GNU/Linux) that's used by millions of individuals, organizations, and for-profit companies.
