This is not true at all.
Of course, always use encryption to ensure your privacy, but there's
nothing about 'cable modems' that make them any more insecure than
the next network access device. There's as many different cable
modem MAC level schemes as there are vendors. Also, because you
can see machines in the network neighborhood doesn't neccesarily
mean you can sniff anything but broadcast traffic. Most cable
modem's in use today by default filter out all traffic except that
destined to the customers and broadcast MAC addresses.
