Naw, he's pissed cause he can't sell camera profiles to people using Camera Raw/Lightroom...
:~)

No, I'm pissed because if my lighting happens to be spiky, or my camera happens to be a strange sample, or, or, or, I cannot just compute a matrix and tell LR or ACR to honor that and be done.
This is not a software difficulty, it's a conscious decision by Adobe not to allow the user to input a matrix. And also ***not honoring whatever matrix is already there in the Raw file's tags***.
It's not a technical issue, all the hooks are already there. ACR and LR use a matrix, but it's always their own (interpolated) matrix -except maybe when reading DNG. The rest of the world would like to be able to mandate the use of a different matrix.
And yes, incidentally, this closed door policy does lock out third party camera calibration tools, and color consultants.
This issue keeps cropping up again and again in the small world of camera color management. I raised it with Thomas at Photokina, asking for profiles - no luck. I raised it with Manish at CIC in Albuquerque, asking for matrix input on the behalf of Xrite; it was again raised at the ICC meeting in Munich last month. It will probably again surface at the meeting in June if the camera guys decide to write their preferred matrix into the TIFF/EP files. It's a political problem with Adobe intent on keeping their system locked down and the rest of the world wanting it opened a bit.
There are increasingly color management technologies that could be brought to bear on Raw color fidelity in much the same way as spectros and printer linearisation can be brought to bear on print color. Various camera calibration technologies have been published or demonstrated, the latest of which is Dietmar Wueller's spectral response measurement device which was described to the ICC digital photo workgroup in Munich. But nobody can get these things to the user employing ACR and Lightroom because of the lockdown.
Oh, and by the way - hint, hint, I'd be delighted to talk in person to anyone ...
