Yeah, so it's not fibre, and should not be sold as such. Not saying HFC is bad (it's actually an awesome way of reusing a deprecated cable TV network), but it's not fibre.
HFC for example is a shared medium across the entire neighbourhood, and in fact if you get root access on your modem and run tcpdump on the HFC interface you may see everyone else's packets as well - there's optional encryption built into DOCSIS but I've never seen it enabled.
