I think Broadbandings is more concerned that the power supply may cause the modem to interfere with the cable network. Which it might, if the power output varies enough.

There's also the concern that if you are found to be using a non-VM power supply and something dies in the future, the engineer might just blame that, replace the lot and charge for the service.
