It's afternoon in Europe, and folks generally don't like to be reminded of the fact that their market is decreasing in global relevance.

In this case, ads are even a product people actively want to avoid, but it's still unsettling to be undesirable. Imagine banning smoking and then getting upset that Philip Morris doesn't want to sell to you anymore.

I don't think many Europeans are lamenting that companies are advertising to Americans more than them.
