Or Amazon has an important role in the new Virus Economy, and is stepping up to do its part.
Sure it sucks for those who work for Amazon, ideally they should be given a choice, but people are not going to stop buying things if Amazon is way behind and orders are looking at a week or two shipment time. They'll go out in public to stores full of other people. This seems like the lesser evil of two bad options to me.
Right now, yes those workers are at greater danger than not working (and maybe they deserve extra pay here) but I would argue that for the public good Amazon better than in person stores at the moment.
