Accuracy is not pedantic, especially when claiming something which is impossible. If customers don't care about availability than they also don't care about the difference between CP or CA, so why not just stick to CP which is real?

Perhaps disingenuous was too harsh, but my issue is that it took plenty of time for CAP to be well-understood and this marketing material does more harm than good by creating confusion. There are better ways of product marketing that don't try to fudge descriptions with technicalities.
