Why would it be fair to suggest such a thing, when there's zero
verifiable evidence for it, and published accounts (e.g. Levy's) to
the contrary? See:

Because the published record states that the original sboxes were weak
against the attack and that NSA sent them back new ones. It's also
fair to say the NSA probably didn't know about LC though as the sboxes
are far from optimized against that attack.

Of course I guess it's hard to tell without the original IBM DEA sboxes
we can't tell if they were weak or not. Fair enough.
