OpenBSD have already decided to disable hperthreading on the OS, probably not a huge headache for Intel because of the relatively small market share held by OpenBSD.
But if Microsoft decide to go down the same route and disable hyperthreading in Windows with an update this will be bad press for Intel as they can't really continue to advertise the advantage of hyperthreading if it isn't functional on the largest OS platform.
Biting the hand that feeds IT
