The whole point is that when a new industial building of ant type is built, don't build it in residential areas.
To use page load for a web page as an argument for locating the datacenters in a residential area is pretty silly. The data travel at the speed of light. Whenter the data come from the next door building or in some industrial area away from resideltial areas has no impact on page load.
If the industry was there first, it is a different issue, but that is not what is being discussed here.
