This is mentioned in the article, but it's important to know that this is not just some Italian novelty, there has been a worldwide effort to figure out how to tax digital services provided by multinational companies in a way that makes sense and avoids funny business with transfer pricing and other tax loopholes, see https://en.wikipedia.org/wiki/Base_erosion_and_profit_shifti....
