The use of free software or open source solution is perceived as a risk for many potential beneficiaries if we talk about professional use either by companies or organizations. While there are potential problems to consider any option, we cannot allow our prejudices move us away from finding the best solution whatever the model chosen to develop it and distribute it. We must challenge certain ideas that come from the traditional model like there must be someone behind taking responsibility because, remember it well, that many times does not solve much. Studying various sources we can see how the arguments for and against either model are always debatable. My conclusion is that we must look at each case, and to each need, to make a decision. The reality is always complex. In that case, above positive and negative points, we’re talking of things to consider. In any case, it should be clear that any solution has a cost that cannot be zero and the target. In exchange for financial accessibility, free software will ask you to devote more technical resources. On Nexe, for example, we apply some positive discrimination in favor of free software for strategic reasons beyond the company itself. We believe that the open development model provides benefits to the community and should be supported. We and many other companies do the technical effort and our customers benefit from affordable applications. Furthermore we find surprises when comparing overall quality of the applications. In a study of the company Coverity, dedicated to evaluating the quality of software, concludes that open source begins to overcome proprietary one in some fields.
