This is nothing to do with one-way/two-way door decisions, you are conflating that concept with an understanding of "unintended consequences" in order to take a cheap shot at Amazon. Ordinarily I'd enjoy that as much as the next person, but this case is too ham-fisted to leave unchallenged.

You're missing the point. The point is that even the most mundane decisions can lead to irrevocable negative situations, so one should think about worst case scenarios with every decision, as engineers are regularly trained to. Classifying things as type 1 or type 2 decisions can create a blind spot, as it did in this situation in my humble opinion. In reality anything can become a one-way-door decision.

The "dunk" is a side effect. Amazon's decision making on this issue does a really good job of illustrating situations where you make a seemingly harmless decision that you feel you could revoke at any time, but things take a turn for the worse and regardless of your ability to revoke the decision, you can't revoke the damage it caused, the preventing of which is the whole purpose of having this system of type 1 vs type 2 in the first place. AKA the type 1 type 2 system is imperfect and can lead to miscalculations, like this. A more useful framework might be "can I prove, convincingly, that there is a 0% chance this decision will lead to irrevocable significant negative consequences, if so then it is type 2, otherwise type 1"

A proper 1 way door for your example would be to build warehouses in a way where cell phones don't work. Once people have died, you cannot make a change to allow cell phones quickly and cheaply. You're stuck with the warehouses, and either have to stop operations and build new ones, or accept the risk that more people will die

2 way doors aren't about making bad choices, they're about the response time and cost for when you identify that the choice was bad. You can make bad choices for 1 way and 2 way doors.

The best example I can think of for your argument is the flint water system. What looked like a 2 way door was actually a 1 way door, when the choice to switch water sources completely destroyed the pipes beyond usability, and any water flowing through the pipes would be contaminated, regardless of the source.

A 2 way door equivalent would stop being contaminated once they switched the water source back, even though people had drunk contaminated water

I understood you perfectly; I simply don't agree. Your model for decision-making bears no resemblance to reality at Amazon or anywhere else.
