The HN headline doesn't fit the article. UK issued Visa cards != Amazon UK, and it says Amazon.com, not Amazon UK. For example Revolut is available in a lot of countries, they're UK-based, and I'm guessing the cards are UK-issued since a lot of merchants think it's a GBP card (and they conveniently ask if they should do the currency conversion (and conveniently don't tell you their conversion rate is much higher and profits them)).
