I agree that they don't get the concept of the Internet, my reading of dublinben's comment is that the issue is deeper: even the article confuses the Internet (the wiring, routers, etc.) with the web (the pages and software/servers). The sarcastic word 'Interwebs' came about to poke fun at those who didn't understand that difference.
