The best way to filter out unwanted users is to make them install software that just displays a webview of what could have been a completely open web page. That way, you only get the ones you can track, which is more important than their wealth, as poor customers often end up spending more on commodity items than someone who is wealthy.

In my experience, Apple and Google are the worst offenders at software bloat, maybe because they can afford to create releases every few weeks, so the bloat accumulates faster.
