You can’t open source it but the government could nationalize it and make it a benefit to small businesses everywhere without the anti competitive profit seeking motives of a private business controlling it.

The original commented suggested that an open source Amazon was the “real solution.” Open sourcing Amazon’s software and then nationalizing their distribution network is a very different suggestion!

Expropriation is the first step to destroying the thing. There no reason for unbelievably good customer service if you get paid by taxpayers regardless of outcome.

The employees at my local usps are pretty good at their jobs. But they are all Korean ladies.

The infrastructure of a large ecommerce website is extraordinarily complex as well, as well as issues that arise with warehousing tech.

You're talking about the infrastructure for a specific seller, which in itself is by no means trivial.

What you want here is an open source replacement for Amazon's product search that will find products from multiple independent sellers. The hard part is probably how to curate it; you want to allow legitimate small sellers without allowing the thing to be filled with scams. But Amazon hasn't done a very good job here either, so maybe it's not a high bar.

And then a payments system which is something in the nature of GNU Taler.

Amazon's logistics is an advantage, but is it an advantage that can overcome the need to pay them a vig instead of having the product shipped directly from the manufacturer? Lots of people willing to wait a week for shipping if the price is 10% lower.
