Z:gnu-www-ja-free-software-for-freedom--f42f24-The relationship between the F/en

The relationship between the Free Software movement and the Open Source movement is just the opposite of that picture. We disagree on the basic principles, but agree more or less on the practical recommendations. So we can and do work together on many specific projects. We don't think of the Open Source movement as an enemy. The enemy is  proprietary software.
