It does not need to be fundamentalist, it can also be utterly pragmatic. If counted the number of times that proprietary vendors have let me down, with no recourse (e.g. the cancellation of BeOS, software vendors moving to outrageous subscription schemes, Apple replacing Spaces by the Mission Control), it would be pragmatic to stop using proprietary software. Since with FLOSS software the community could maintain something ad infinitum when there is interest. (Disclaimer: I do use some proprietary software.)
