Some advanced features are left out, in part, because they generate expensive support calls. E.g.. AFMA is not useful to many Rebel Users, but would probably generate a lot of self-inflicted focus wounds.
Classifying a "feature" as "advanced" is irrelevant. What matters is whether it is purely firmware-based and excluded. If so, then the camera IS deliberately crippled ... and thus both neuroanatomist and unfocused are wrong. So what do YOU want to be: right or wrong?
I always find your black/white thinking amusing...or something.
You're pulling out your personal definition of "crippled:" to my mind, it's not merely a matter of whether a no-cost feature was removed, but whether that feature would be expected to be used by the vast majority of users of the product.
For example, removing the "Japanese" language features from a product that's being marketed in China, but not in Japan, can't really be considered crippling since one can't reasonably expect that feature to be used.
You should re-examine your logic when you find yourself mincing words to manufacture a "win."
