The reality is, your core user base is always your easy-to-get captive market that intrinsically want what you do. A corollary of that is that gradient towards more users is always going to be eating into people more at the fringe or even totally outside the core intent of your product or service. So intrinsically, optimising for them is very unlikely to be optimising for your core users.
We can believe a fairy tale where we tell ourselves that we can optimise for new users while still maintaining equal service for existing users, but it's really just a fairy tale - invariably these things end up in competition with each other.
