Well, first off, "new" is a relative term. If you're new compared to folks who have been your customers for a decade, you can still expect several years of good service, which is probably enough for now.
The new folks are more used to the CCGs and videogame models, where games change pretty constantly. They may not be expecting the decade or more of support that some of the older players do.
And, to be cynical, the new players don't know much about how players of older editions feel they were treated, and they probably don't much care, either. For one thing, not every customer of old feels put upon (I don't, for example). The ones who do feel put upon, I fear, paint themselves in such a poor light as to make the newer players... glad that they aren't around.
