It wouldn't be surprising to hear that Lange had been under some pressure to drop Appelbaum or at least account for his position in her group (so far as I know, Appelbaum had no undergraduate qualifications to join it).
I think it's fair to say that Bernstein wrote his article in response to the whole Appelbaum story. But I didn't read him taking sides, so I'm not seeing a conflict of interest (unless he's a lawyer/judge/etc :) ).
