> There may be some use cases for hubs still, but generally they should be avoided.

There is no such thing as a hub for modern wired Ethernet anyway; Gigabit Ethernet requires switches and full-duplex links.

(One thing we used to use hubs for is security monitoring: run your Internet traffic through a hub and attach the intrusion detection system(s) there; since the hub mirrors all traffic to all ports, your IDS can sniff it all. These days you'd use a network tap or a span port for that.)
