Im confused as to what it is that you want? In general yimbys want strict zoning laws “softened” so that multifamily homes and other alternatives to single family homes can be built in a particular area.

People advocating for that in one area doesn’t preclude it from happening elsewhere. While I agree that the developers need to start paying attention to other parts of the city it’s not like this group is actively courting them and paying them off to only develop north of the river. If anything I would think this group would be happy to see that kind of investment in poorer areas as well.
