I disagree that it's bad, it's a choice. You can't protect against everything. The team made calculations and decided that the cost to protect against this very low probability is not worth it. If all the nodes lose power you may have a bigger problem than that

Power outages across big areas are common enough.

It's downright stupid if you build a system that loses all existing data when all nodes go down uncleanly, not even simultaneously but just overlapping. What if you just happen to input a shutdown command the wrong way?

I really hope they meant to just say the write buffer gets lost.

That's why you need to go to other regions, not remain in the same area. Putting all your eggs in one basket (single area) _is_ stupid. Having a single shutdown command for the whole cluster _is_ stupid. Still accepting writes when the system is in a degraded state _is_ stupid. Don't make it sound worse than it actually is just to prove your point.
