This article also makes it even more complicated by calling the C in CAP "atomic consistency". While technically correct as that means the same thing as linearizability, that term is rarely used in comparison. When comparing the overlapping terms in CAP and ACID it just seems excessive.
'Atomic Consistency' is used in the CAP proof. YMMV, but I've seen it more used than 'linearizability' (it's easier to pronounce...). Agreed, there is no confusion when you use linearizability.
