" The idea of open source is that allowing users to change and redistribute the software will make it more powerful and reliable. But this is not guaranteed. Developers of proprietary software are not necessarily incompetent. Sometimes they produce a program which is powerful and reliable, even though it does not respect the users’ freedom.

The free software community understands that free software gives the user more freedom than proprietary software. Proprietary software confines its users, prohibits them from making changes that would allow everyone to benefit, etc. Free software advocates (myself included) have a habit of claiming that using free (libre) software means the same thing as having freedom.

“Open Source” advocate: «...I associate much more with the "Open Source" (also as Richard defines it) camp, and am open to the existence and use of proprietary software...» --

RMS: «When we call software “free,” we mean that it respects the users' essential freedoms: the freedom to run it, to study and change it, and to redistribute copies with or without changes [...] As the advocates of open source draw new users into our community, we free software activists have to work even more to bring the issue of freedom to those new users' attention.

As a lawyer, law professor and software programmer, Eben Moglen is passionate about technology, software and user freedom. A former board member of the Free Software Foundation and the founder, president and executive director of the Software Freedom Law Center in New York since 2005, Moglen has worked to protect and advance open source and free software.

"Once software users freedoms are protected the methodology that we know as Open Source becomes possible and its advantages become apparent. But without the guiding principles of Free Software the neccessity and direction of Open Source cannot be accounted for. Open Source has no history or trajectory, it cannot account for itself or suggest which tasks are neccessary or important.

"As the advocates of open source draw new users into our community, we free software activists have to work even more to bring the issue of freedom to those new users' attention. We have to say, “It's free software and it gives you freedom!”—more and louder than ever."

"Open source is a development methodology; free software is a social movement. For the free software movement, free software is an ethical imperative, because only free software respects the users' freedom. By contrast, the philosophy of open source considers issues in terms of how to make software “better”—in a practical sense only. It says that non-free software is a suboptimal solution.

Last April (April-29-2010) there was a local event in Ecuador organized by AESoft, the Ecuadorian Software association. This event was names “Integrated Technologies” and was sponsored by Microsoft, CodePlex, Port25 and The Apache Foundation. On this conference Microsoft sent a message saying that they are Open Source friendly and they support Open Source development.
