I guess I'm not reading it that way. In fact, a FOIA request is going after official records, which I wouldn't expect would contain outright bribery.

Yes, DJB brings up their known bribing of RSA wrt to the whole Dual-EC thing. But my read of that bit of info was the more general 'here's evidence that the NSA actively commits funding towards infecting standards' rather than 'the NSA's playbook just contains outright bribery and that's what we expect to find in the FOIA requests given to NIST'.
