They should be building those things on the far side of the Moon instead. Radio telescopes suffer from interference from terrestrial radio sources, which is why they locate them in the middle of nowhere, West Virginia, but even that doesn't fully isolate them. Putting them on the far side of the Moon would (at least for a while) completely eliminate problems with terrestrial interference, plus give humanity a good reason to back to the Moon and build some serious infrastructure there, and perhaps also distract us from fighting with each other so much. It would also give many engineers something much more important and useful to work on than ad-ware.
