Read more -still not getting it. "Breeding corruption" is a throwaway line. How? What happens? Folks use the software in some way, that interferes with the open-source users' own use? I can't see that happening.
I guess I'm obliquely commenting that keeping the project small and in the hands of open-source developers, may be pointless. Otherwise, why agonize over what others are doing with it? Either we want others to use the open-source version too so its a popular desktop with lots of attention, or we don't and becoming a popular desktop with lots of attention doesn't affect those open-source die-hards at all. Either way, a successful project becomes popular on a lot of desktops.
