They were discussing University licenses and legal battles that lead Gosling to include a license in his source for Emacs.
> Gosling: But then then there was at one point I kinda realized at one point um I was ither I was ither going to be Mr. Emacs for the rest of my life or graduate. I couldn't actually do both um so I decided I wanted to graduate.
> Interviewer: So then but your display algorithm got incorporated by Richard Stallman into GNU Emacs?
> Gosling: Well Actually it was more than that. He just took all the source code.
> Interviewer: oh ok
> Gosling: Right? It was.. It started out as all of the source code and he just edited the copyright notices.
> Interviewer: Really? So he just essentially stole your program?
> Gosling: Yeah so um
> Interviewer: And claimed it as his own?
> Gosling: Yeah
At this point Gosling reiterates his revelation about either graduating or remaining "Mr. Emacs" and the explains how he went around to "all the usual suspects" at MIT and UCLA asking if anyone wanted to take up maintenance of Emacs. Everyone turned him down, including Stallman who Gosling said responded with a "frothing hell no" and explained that Stallman's position was that Unix was the spawn of the devil.
Gosling then discusses University licenses, litigation, IP, and opensource as reasons why he decided to license Emacs and ask for letters acknowledging the license from people he distributed the source code to.
Gosling then explains how the license for Emacs ended up with two guys in a garage but never actually says that he sold it to them, just that Emacs should remain free for universities. He explained how when Stallman found out about the license transfer, Stallman freaked out. Gosling then expresses some remorse he felt for the two guys in a garage because Stallman proceeded to release GNU Emacs and, despite legal victories against DEC and IBM, the two guys were force to abandon Emacs because they had no legal recourse against Stallman.
The interviewer then asked why no one went after Stallman and Gosling explained that Stallman was essentially homeless and you gain nothing from suing a homeless man. Gosling was trying to explain delicately and uncomfortably that Stallman had different views on economic models when the interviewer then took a jib at Stallman's hygiene. Gosling, who is already visibly uncomfortable discussing the topic, deflected by saying that they had different opinions and that Gosling preferred to have food on the table and a roof over his head.
