Resumen
Sooner or later, every successful open-source software package will have one or more profitable businesses associated with it. For example, the Linux operating system is supported by several companies including Red Hat and Caldera, the GNU tools are supported by Cygnus, the Sendmail email delivery system is supported by Sendmail, Inc., and the Tcl scripting language is supported by Scriptics. This association between open-source software and business is not just a historical artifact, but a necessity On its own, open-source software lacks essential ingredients for mainstream adoption. Commercial businesses tied to open-source packages provide these ingredients and help drive open-source packages into the mainstream. At the same time, they provide additional resources for developing the free components of the software. Some free-software purists object to the commercialization of open-source software. They believe that the most important aspect of open-source software is that it is free, by this standard, any association with proprietary products tarnishes the software.
