The book focuses on penetration pricing and lock-in as tools to maximize profit, not as a means to support the free software community. In a paper written a few years later the same authors note: "The very idea of having "conditions" accompanying a "free" good confuses some people, and opponents of open source software have done their best to amplify that confusion." (See Linux Adoption in the Public Sector: An Economic Analysis, Dec. 2003.) I think what the original poster (Jordi) is concerned about is that there are conditions (spelled out by FSF/GPL) that do not seem to be followed in practice. See, for example, http://www.gnu.org/licenses/gpl-faq.html#GPLInProprietarySystem It is important to remember that the FSF/GPL conditions are in addition to Copyright law, that Copyleft is an extension of Copyright, not in opposition to it. In particular, the Copyright holders of software released under GPL are free to release the same software (possibly with a few extensions) as a proprietary product, without including any source code. The Copyright holders are also free to permit others to violate the terms of the FSF/GPL, because only the Copyright holders are in a legal position to enforce those terms. (In practice things are complicated by the viral nature of GPL and by the growing set of Copyright holders over time.) This may not seem "fair" to some, but I think it is legal (check with a lawyer to be sure). Dominick > I've used Matlab, and I want to start using Octave.
