I think it's a mistake to only look at margins. We should also look at economies of scale. In the future, as margins get lower, it is compensated by more customers. Also, whenever margins get lower, successful businesses tend to provide additional value and charge for it. It is already happening in cloud services. Few years ago, it was fully IaaS and now it's moving towards more PaaS. Who knows what will come next? I can already see so many things that could be done better, and that's just me.
