> A feature that was possibly accidentally enabled on consumer chips is now being disabled.

Bro what are you smoking? The highly paid and experienced engineers designing these chips could have "possibly enabled" the feature on consumer chips.

The chips were designed with the feature as it is cheaper to do everything right from the get go and disable functionality rather than design a less capable chip then tack on the feature afterwards, just as the consumer versions of Windows are the server versions with functionality removed.
