Nobody's going to make any money just by aggregating & providing access to data points. Geo isn't as hard as everyone thinks it is. PostGIS absolutely does intersects with arbitrary polygons, for example. Where people will make the money is by providing new, interpolated data layers; it's one thing to say "get the weather at location X!" and another to say "show me the best intersection to get a cab" or "show me where the closest taco truck is likely to be given today's weather & past behaviour". I understand Simplegeo was trying to provide the access to the data to enable people to answer these questions themselves; why not just sell them the answers?
