Re: The beginning of the end
Linux and BSD have been successfully commercialized as viable user OSes as ChromeOS, Android, iOS, and OS X as wells a few solid commercial traditional Linux distros. But your point Slurp will be around for awhile before it becomes another marginalized player or completely disappears is quite correct.
A far as FOSS developers not caring about about power users or end users misunderstands that FOSS projects often begin life as someone trying to fix a problem. Often the project, particularly in the early stages, does not have a wide perceived target audience because the developers are not doing marketing surveys, marketing plans, etc. It's often later when they realize there is more interest in the project that start to address the other needs.
