You are right, but with DOCSIS, you're generally sharing an order-of-magnitude smaller bandwidth allocation with many more users. Around here, there's 4 upstream channels available (roughly 120 megabits) shared across at least 200 homes.

Downstream is better, but it's still around a gigabit shared (32 DOCSIS channels.) Then you need to consider the RF issues that constantly plague cable networks, like ingress. Based on my personal experience, it can take months to get this fixed, if they'll even believe it's a problem. They'll open ticket for "outside plant" and not fix anything. At one point, I saw my upstream drop below a megabit! (And no, it wasn't my wiring or equipment.)

I recently switched to fiber, and it's night-and-day.
