First off, just because something is developed in the public sector does not make it Communist. If you don't know what words mean, don't use them please. I don't have time to go over definitions.

Secondly, the ground work for undersea cables, radio towers and satellites were indeed a direct result of work and funding from the public sector. The private sector wanted nothing to do with the internet until the mid 90's when enough work had been done that it was deemed "profitable".

A better example of what Capitalism does best would be adding advertisements to the internet, or the fact that Americans pay more per megabit than any European country on average.
