“In the context of software development, where you have sequential and complementary developments, patents create an extraordinarily damaging influence on innovation and on the process of developing and bringing new ideas to market.”
"Code + Law: An Interview with Lawrence Lessig" at O'Reilly P2P (29 January 2001)(29 January 2001)
Context: Our problem is that lawyers have taught us that there is only one kind of economic market for innovation out there and it is this kind of isolated inventor who comes up with an idea and then needs to be protected. That is a good picture of maybe what pharmaceutical industry does. It's a bad picture of what goes on, for example, in the context of software development, in particular. In the context of software development, where you have sequential and complementary developments, patents create an extraordinarily damaging influence on innovation and on the process of developing and bringing new ideas to market. So the particular mistake that lawyers have compounded is the unwillingness to discriminate among different kinds of innovation.
We really need to think quite pragmatically about whether intellectual property is helping or hurting, and if you can't show it's going to help, then there is no reason to issue this government-backed monopoly.

Context: Isn't it ironic that the proprietary software developers call us communists? We are the ones who have provided for a free market, where they allow only monopoly. … if the users chooses this proprietary software package, he then falls into this monopoly for support … the only way to escape from monopoly is to escape from proprietary software, and that is what the free software movement is all about. We want you to escape and our work is to help you escape. We hope you will escape to the free world. The free world is the new continent in cyberspace that we have built so we can live here in freedom. It's impossible to live in freedom in the old world of cyberspace, where every program has its feudal lord that bullies and mistreats the users. So, to live in freedom we have to build a new continent. Because this is a virtual continent, it has room for everyone, and there are no immigration restrictions. And because there were never indigenous peoples in cyberspace, there is also no issue of taking away their land. So everyone is welcome in the free world, come to the free world, live with us in freedom. The free software movement aims for the liberation of cyberspace and everyone in it.

Pitää olla myös poliittinen näkemys siitä, mihin maat ja alueet ovat kehittymässä, sekä poliittisia valmiuksia vaikuttaa kehityksen suuntaan, esimerkiksi ihmisoikeus- ja turvallisuuskysymyksiin.”
