Note that what courts are blaming Amazon for is not to deliver unnecessary goods, but to not care enough for the security of their employees in their warehouses.

So basically, it's not a problem for other delivery services who took stricter safety measures.

If anything, telling them they can still continue deliver necessary goods is a bit lax, because their employees are not safer processing those.

The Amazon answer is quite unbearable, to be honest. Basically, it's "people can't live without us, so we should be above the law". It's time to show them we can live without them.
