A misunderstanding is circulating that the GNU Project demands you run 100% free software, all the time. Anything less (90%?), and we will tell you to get lost—they say. Nothing could be further from the truth.
Our ultimate goal is digital freedom for all, a world without nonfree software. Some of us, who have made campaigning for digital freedom our goal, reject all nonfree programs. However, as a practical matter, even a little step towards that goal is good. A walk of a thousands miles consists of lots of steps. Each time you don’t install some nonfree program, or decide not to run it that day, that is a step towards your own freedom. Each time you decline to run a nonfree program with others, you show them a wise example of long-term thinking. That is a step towards freedom for the world.
If you’re caught in a web of nonfree programs, you’re surely looking for a chance to pull a few strands off of your body. Each one pulled off is an advance.
