Throughput is proportional to bandwidth and is logarithmic with SNR (i.e. output power). All being equal, you'd rather they use a narrow signal with a lot of power than a wider one. The greedy/lazy/polluting way would be to demand a wide allocation so that you can use low power. Of course, a very loud signal right next to amateur allocations may mess with lower-quality receivers.
