As in everything else important, there is a balance to be stricken between stagnation and upheaval. When choosing platforms, how communities weigh this balance is a very important consideration. You want to associate with people and groups who value essentially the "reasonable breeze" mode that keeps life flowing through extant systems. "Natural disasters" may sometimes be justified to help clear out the way-too-old (e.g. systemd or SMF), but they should be rare; systems can only tolerate major disruptions like that once or twice a decade. Linux has an "anything goes" approach, which is usually more symptomatic of the age/maturity of the crowd it draws in than a reasoned decision about where to fall on this balance. That's not necessarily bad, but it makes more of an experimental atmosphere than something reliable, trusted, and stable.
