This is one of those episodes where I think “hey, I’ve got something to say about this on the forum” but by the end I’ve got so many disagreements and comments, along with some agreements, that’s it’s just not the best form of discourse for such a topic.
But here is one point to start:
European anti-trust is about conserving or improving the state of competition between companies. The idea is that if competition is upheld, the customer is served better in the long run. This means that short-term pain is put on end users and customers, but hopefully the better product/service will win out. That’s why Microsoft had to add a browser picker in Windows.
But in America, the focus is on the good of the end customer. This means that in a monopoly that exists because the product is the best, and continues to be the best for customers, like Google Search, telling customers they have to be customers of a different company that might not be so good actually hurts the end customer.
So in Europe, it’s not like they are punishing American companies per se, just that they have a different framework for anti-trust that, as a by-product, helps European or other non-American companies.
