Advertisement of "hubs" doing half-duplex operations?

The other day I found links of vendors stating that a certain hub model could deliver half-duplex configuration.

Is that just a wrong name for a hub? If a "hub" can do half-duplex, that is a technically a switch. Is that conclusion right?

No, it's the opposite.

Hubs operate in half-duplex mode - they enlarge collision domain.

Switches can operate either in full duplex or half duplex mode. In full duplex mode each cable is it's own collision domain, therefore microsegmenting your collision domain and reduce collisions virtually to zero.

Ah. Pardon me, I meant, I saw some ads of people saying that certain hubs could operate at full-duplex. I guess that's just a label issue I guess, since we know that hubs *never* operate at full-duplex.
