Ben is being witty... he certainly is very aware of the possible uses of this piece of hardware, and he's also intellectually curious about how to take advantage of cheap hardware interesting ways (and network protocols, etc). The rest of his blog should hint at this depth, but he's just light-hearted, curious and fun with this stuff. Bear in mind he brought us BGP Battleship https://blog.benjojo.co.uk/post/bgp-battleships and runs his own AS (because you can!).
