He most certainly did not. In fact, you already legislated this exact point with him and he explained exactly why he made the choices he made -- in your own comment history.
I did exactly what he tried to do. It took me less than 1 hour and my node was in sync.
If you use a dedicated server with sufficient bandwidth and not your laptop at home for a fullnode this can easily been done.
IOT devices are connected to this fullnode and are not fullnodes themselves. I dont know what made him think otherwise.
