Several transceivers connected to the same cable allow
several machines
to communicate. In a sense, the transceivers together with the coax cable
form the hub.
The T-pieces are, indeed passive (all 3 connectors connected in parallel
in the obvious way), but they're not really the hub.

It's really that the hub doesn't exist on a bus network like 10Base2
or 10Base5... all the Tee connectors are doing is replacing
the vampire tap on thicknet...
The thinnet "Transceiver" is really built on to the card on
most PC's and is the same (basically) as the old thicknet
transceiver attached to my Sun my Unix boxes -- they can go from
Thinnet to Thicknet by swapping the N-Connector top to the
BNC connector top. And thinnet can go to thicknet with just an N to BNC
adapter -- but the max length and specs drop to thinnet specs.
Hubs really distort the logical ethernet bus topology.
Now 10/100 switches really screw with it.
