The US is very different from Europe. You have enormous amounts of space so even a Data Center that is "close by" is probably still a mile or more. In smaller places like European countries, the data centre wall might only be 100 yards or less from the back of your house so the proximity blocks light and makes you feel encroached on, even if no-one is peeping. In lots of cases, the center might have been built on open land so it is not surprising people don't appreciate their view changing from open land to "very large and tall building"
