I don't think this is about supporting chromecast for Amazon Video, it's about actually selling the google chromecast itself on amazon.com.

I don't think there is any argument that passes the sniff test for them not to be able to sell a physical device like chromecast from amazon.com. The level of incremental work is basically zero to add an item into the store.

They banned even third party sellers from selling chromecast. You can sell basically whatever you want on their site, except for chromecast and apple tv.

There are exceptions to "sell anything", but chromecast and apple tv are the only business exceptions, not based on safety/legallity/ authenticity etc.

You're confused. Amazon didn't just refuse to integrate with Chromecast, for their Prime videos or whatever. They refuse to carry Google's product in their inventory, period. You can't buy a Chromecast on Amazon.

That IS pretty much directly comparable.

I think it was less that Amazon wouldn't provide support for Chromecast with their services and more that they refused to stock and sell Chromecast devices at all.

I suppose the difference between this and Walmart's move is that we are not entitled to buy the things we want from every shop, whereas these drivers are probably entitled to employment without discrimination in regards to other customers they provide services to?

The work to support it? They just refused to list it on their marketplace/products
