Free Software developers fall into two main categories: those that stand by the principles behind free software - patent-free, license-free and unrestricted distribution (for example, Richard Stallman's admirable stance); and those that are simply happy to compromise to some extent, for example to download libdvdcss to watch DVDs, or to install proprietary software such as Skype, on the basis that there is simply no (or no better) alternative (for example, Ubuntu which supports all kinds of proprietary firmware and binary drivers, and gets itself into enormous difficulties as a result).
