GNU - GPL - Free Software

What is free software and why is it so important for society?


"Free software is software that gives you the user the freedom to share, study and modify it.  We call this free software because the user is free.

To use free software is to make a political and ethical choice asserting the right to learn, and share what we learn with others.  Free software has become the foundation of a learning society where we share our knowledge in a way that others can build upon and enjoy.

Currently, many people use proprietary software that denies users these freedoms and benefits.  If we make a copy and give it to a friend, if we try to figure out how the program works, if we put a copy on more than one of our own computers in our own home, we could be caught and fined or put in jail. That’s what’s in the fine print of the license agreement you accept when using proprietary software.

The corporations behind proprietary software will often spy on your activities and restrict you from sharing with others. And because our computers control much of our personal information and daily activities, proprietary software represents an unacceptable danger to a free society."
