In my exchange with Anna at id about the leak (above), I also learned that the audio transcripts posted earlier were not authorized for release. Here is what she said about that:

Negotiations were under way to secure an interview with the id team by Mat Bettingson. Due to id's limited time, discussions led to a visit in April. However, Mr. Bettingson came to our offices in February under false pretense and without a proper appointment. According to Mat, he had been told that arrangements for a February interview had been confirmed. A courtesy was given to Mr. Bettinson because he had flown from the UK and we believed that his intentions were honorable. Rather than tell him to simply pack his bags and return to the UK empty handed, we treated him with respect and gave him time with members of the development team in addition to giving him the opportunity to check out Quake III Arena. The understanding was that Mat would be doing a written article on Quake III Arena, nothing more. As a general rule, it is allowed that reporters bring audio equipment to assist them with their notes. However, it has never been the case that these recordings be displayed as audio files. A courtesy given was severely abused and the damage from this unprofessional behavior has resulted in distrust and lack of confidence. We are requesting a formal apology and the termination of any release of audio files.

As a result, I have pulled the copies of the interview that I had mirrored.
