About Libre Software
There are two categories of software : those which are proprietary and we must usually pay for their use, and those which are libre and we have no obligation to purchase.
Commercial and libre software are not necessarily opposable, and sometimes the objectives have no relationship with their differences that can be mixed according to the domain, the need, the type and the scope of a project.
In both cases, developers supply an immaterial work through a physical medium, for which they are intellectually the authors, and which takes time and investment. The purpose of a work being to live and survive, for oneself and for others, a free software is not thus synonymous of gratuitous.
Donations are a source of income for free software designers. Just like we are free to use these programs, we are also free to define what we give according to our means.
Developing free or open source software is a vision about source code, sharing of knowledge and evolution of computing. You can read different points of view from Free Software Foundation, from Open Source Initiative and from Creative Commons.
