Xanadu was a live feed of a prehistoric computer

Were other satellite positioning systems affected as well? was it checked that it wasn't just a prehistoric "computer". It seems like it would be a mistake to say things like "it was for science and not religion" or vice versa. Additionally, also seems like it would be a bit too on-the-nose.

As the last two paragraphs of TFA point out, this idea is now widely discredited. However, there are a lot of abuse from those services with people using them as proxies or something. It seems like it would be easier for comparison if they both would point in the same direction.
