Warranties and Indemnification ------ 1 This materials have been adapted from Chapter 11 in Raymond T. Nimmer, The Law of Computer Technology (1997, 2005 Supp.).I. Distinguishing Open, Free and Proprietary Software Free software and open source (FSOS) software reflects a philosophy about what is the optimal manner for the distribution and development of software.2 Although it has multiple facets, the philosophy emphasizes making the source code of the software available to transferees of the software and providing the software to others with limited or no restrictions on its use, and with a right to modify and redistribute the software.3 This philosophy is implemented through licenses. It thus has a uniquely law-related core dimension. Rather than substantively precise themes, however, FSOS concepts state a fluid philosophy about software development. There are several different ways to look at this philosophy. One is from the perspective of the core adherents – the founders or participants in the central core that zealously follow and promote the philosophy. It is here that the self-definition of FSOS philosophy is most vivid and aggressive. Many discussions of FSOS concentrate on this aspect of FSOS as if it were the only useful way of discussing FSOS, its philosophy and its adherents. But there are other perspectives. One emerges by focusing on the periphery of the so-called “community.” As FSOS ideas became a broader part of the software development culture and achieved some market attraction, FSOS attracted a broader and differently motivated membership or following than that with which it began. Many involved in FSOS products today generally support the principles, but do not hold the missionary zeal in detailed adherence that the core group manifests. Additionally, many software purveyors are attracted to FSOS by the marketing opportunities it offers rather than by the core philosophy. If one imagined FSOS as a circle, non-zealot participants and aspirants who seek the label as a matter of convenience or market definition, would form a grey area at the edges of the circle and often extending beyond it, at least as the circle were defined by the core participants. This is an increasingly heterogeneous community. A FSOS Compared to “Proprietary” Software 2 See David McGowan, Legal Implications of Open-Source Software, 2001 U. Ill. L. Rev. 241, 268, 274 (2001); Greg R. Vetter, The Collaborative Integrity of Open Source Software, 2004 Utah L. Rev. 563. 3 There is an intentional distinction here between unrestricted use and the “right” to distribute in original or modified form. While the former is typically unrestricted under licenses that conform to FSOS dogma, the latter is often subject to significant restrictions grounded in an effort to advance or protect FSOS philosophy as applied to the software. 2What then distinguishes between proprietary and FSOS software? The answer is simple. The distinction was created by the FSOS community to indicate that those within the community and how they behave are different from the identity and behavior of “the others.”4 If you distribute software consistent with FSOS community norms, from the perspective of the community, yours is FSOS software. If not, from that same perspective, yours is proprietary software. Indeed, the leading “free software” organization defines “proprietary” as any software distributed under terms that do not meet the standards of FSOS.5 The idea that FSOS software is one thing and that “proprietary software” is another resonates within the open software community. But for third-party understanding of FSOS, the definition is not always useful and it is unstable. B. FSOS compared to public domain software Free and open source software (FSOS) is not equivalent to public domain software. While FSOS software is not public domain, some FSOS technologists assume that are contributing to the public domain by releasing software under an FSOS license. That is not true. Public domain software is literally “free.”6 It consists of software for which no intellectual property restrictions exist. This might occur because the software code is insufficiently expressive to qualify for copyright protection (even though it may be important in the technology), and too obvious and well known to qualify for either patent or trade secret protection. Alternatively, the software may enter the public domain because the author/inventor of the code releases and abandons all rights to it. A work in the public domain is available for any and all to freely use in any way that they like. They can copy, resell, modify and otherwise deal with it as part of the freely available background that provides grist for new work.7 Included in this is that others can incorporate public domain material into their own, proprietary works and assert property rights
