You can say amazon doesn't pay VAT but it's just as honest as saying Americans don't pay for tariffs
The consumer pays a certain price for a product and a portion of that money goes to taxes and costs to Amazon (including things that are taxed, like driver salaries and fuel). Those taxes are collected on the way from Amazon to the end user in every country they pass through, more or less.
Amazon is creating commerce that is taxed. They aren't skating by for free.
