I just learned that the EFF took on Landmark to stop them from mis-using the DMCA [http://www.eff.org/cases/landmark-and...]. Having sat through Landmark's recruiting pitch I know that they consider their "ideas" as "core technology." In this case they are trying to equate the discussion of the ideas with the specific embodiment of them in the training manual. They're obviously not the same thing, as any IP lawyer can tell you.
Landmark is the descendant of est (erhardt seminar training), the famed human potential seminars of the seventies. Whenever you ask someone from Landmark about what the connection is with est they'll say "we just purchased technology from them." The "technology" is the ideas behind the training, I guess. Given their belief in the proprietary nature of their ideas, it makes sense they'd attempt to shut down films that capture them for public viewing. Particularly on the Internet!
It seems as if they're nostalgic for the AOL walled garden model of Internet services:
AT&T is going to start policing its network to prevent the distribution of materials it considers to violate copyright. (Um, Fair Use?) It's doing this so it can strike special deals with content companies to offer their products exclusively.
