But he actually makes a very specific point:
> This Internet, though, feels like the worst of all possible outcomes. On one hand, large U.S. tech companies are winners, at least relative to everyone else: yes, all of the regulatory red tape increases costs (and, for targeted advertising, may reduce revenue), but the impact is far greater on would-be competitors. To put it in allegorical terms, the E.U. is restricting the size of the castle even as it dramatically increases the moat.
He's saying that under Europe's model, giant US tech companies are going to be even more locked in to dominance. The market will be less competitive, and have less room for European-grown companies to rise up. It's pretty hard to see how any regulations Europe might impose are going to substantially ameliorate the harmful economic effects of US companies dominating tech, and Europe's economy being relegated to the 20th century.
