Infectious nulls mean that the source of your nullness propagates through your data graph, following data flow, until you finally notice some time later, some way downstream, whereupon it's usually a problem.
You generally want problems to be noticed close to their origin, and not hide latently in lists and maps, waiting to be tripped over.
