It doesn't matter what a chipmaker provides and claims as truth today.
Anyone, spy or not, anywhere in the chain from design to fab could
insert anything, there are probably not enough internal control and
validation programs in place to find it. And if something untrustworthy
is sucessfully implanted or simply produced TOP SECRET approved,
who on the outside is going to find it? No one publicly open, external, and
disinterested is sampling these chips off the shelves and decapping them,
or exhausting all possible input data against expected output, or has eyes
in the fabs. Until the world has truly open fabs, you might as well assume
it's game over.

Similarly, we can't even get rid of default firmware passwords, baseband, bad
crypto, closed source, vPro, and all the other examples of potentially
things possibly against the user... including NSA style spying and corporate
datamining tagged with your name.
Can you apply enough pressure to get rid of closed fabs, and the elements
within governments and corporations that think up, perform and produce this
kind of stuff?
