Software has to be designed by hackers who understand design, not designers who know a little about software. If you can't design software as well as implement it, don't start a startup.

The essence of a software entity is a construct of interlocking concepts: […] I believe the hard part of building software to be the specification, design, and testing of this conceptual construct, not the labor of representing it and testing the fidelity of the representation.

The GNU GPL is not Mr. Nice Guy. It says "no" to some of the things that people sometimes want to do. There are users who say that this is a bad thing--that the GPL "excludes" some proprietary software developers who "need to be brought into the free software community."
But we are not excluding them from our community; they are choosing not to enter. Their decision to make software proprietary is a decision to stay out of our community. Being in our community means joining in cooperation with us; we cannot "bring them into our community" if they don't want to join.
What we can do is offer them an inducement to join. The GNU GPL is designed to make an inducement from our existing software: "If you will make your software free, you can use this code." Of course, it won't win 'em all, but it wins some of the time.Richard M. Stallman
In 1998, some of the people in the free software community began using the term "open source software" instead of "free software" to describe what they do. The term "open source" quickly became associated with a different approach, a different philosophy, different values, and even a different criterion for which licenses are acceptable. The Free Software movement and the Open Source movement are today separate movements with different views and goals, although we can and do work together on some practical projects.
The fundamental difference between the two movements is in their values, their ways of looking at the world. For the Open Source movement, the issue of whether software should be open source is a practical question, not an ethical one. As one person put it, "Open source is a development methodology; free software is a social movement." For the Open Source movement, non-free software is a suboptimal solution. For the Free Software movement, non-free software is a social problem and free software is the solution.Richard M. Stallman
Free software permits students to learn how software works. Some students, on reaching their teens, want to learn everything there is to know about their computer and its software. They are intensely curious to read the source code of the programs that they use every day. To learn to write good code, students need to read lots of code and write lots of code. They need to read and understand real programs that people really use. Only free software permits this.
Proprietary software rejects their thirst for knowledge: it says, “The knowledge you want is a secret—learning is forbidden!” Free software encourages everyone to learn. The free software community rejects the “priesthood of technology”, which keeps the general public in ignorance of how technology works; we encourage students of any age and situation to read the source code and learn as much as they want to know. Schools that use free software will enable gifted programming students to advance.Richard M. Stallman
Over the years, many companies have contributed to free software development. Some of these companies primarily developed non-free software, but the two activities were separate; thus, we could ignore their non-free products, and work with them on free software projects. Then we could honestly thank them afterward for their free software contributions, without talking about the rest of what they did.
We cannot do the same with these new companies, because they won't let us. These companies actively invite the public to lump all their activities together; they want us to regard their non-free software as favorably as we would regard a real contribution, although it is not one. They present themselves as "open source companies," hoping that we will get a warm fuzzy feeling about them, and that we will be fuzzy-minded in applying it.
This manipulative practice would be no less harmful if it were done using the term "free software." But companies do not seem to use the term "free software" that way; perhaps its association with idealism makes it seem unsuitable. The term "open source" opened the door for this.Richard M. Stallman
