Sure. But given that the affected customers would by definition not have offsite backup, the comparison is against a smaller operator that has way more risk of fires, theft, bankruptcy, incompetence, earthquakes, power delivery, and all the other risks.

Sure, fewer customers per location, but the critique here is of customers who chose AWS, the fair comparison is NOT against those who chose to be in 6 different non-AWS DCs, but against those who chose to be in ONE non-AWS DC. Decentralized aggregated across customers or not, the customers who chose unluckily still lose data.
