There's still a disturbing amount of software that operates on a per-core pricing model. Some of them include Hyperthread in that core count. When we launched Oracle Cloud Infrastructure, (as Bare Metal Cloud, before we launched our VM product), our standard bare metal instance had 36 cores, 72 threads with HT enabled. One interested customer couldn't use our platform because just licensing their standard software on our platform was going to set them back some $250,000 due to all those 72 "cores". The product manager at the time mentioned there were several other customers facing that issue with their various bits of enterprise software.
