I see this same discussion in the audio world sometimes re Waves plugins, and one big factor there is Windows vs. Mac. Windows users tend to be able to use old, even ancient versions forever with no trouble. Mac users on the other hand, often seem to be faced with having to either pay for a new software version that works with a newer version of Mac OS, or stay on an old version of the operating system - sometimes on old hardware as well.
