I think that my characterization is significantly less controversial. For instance Bruce Perens (original author of the open source definition) says that the open source definition was ...conceived as a program to market the free software concept to people who wore ties.

On the other hand your characterization strikes at the heart of the BSD vs GPL argument as it is viewed by BSD proponents.

Exactly, I'm leaning more towards Eric S. Raymond's developer-centric views, which may not be canonically Open Source but do speak a lot more to me and my personal history pre-1998. But this hopefully answers the question by the gp about why there is room for more than two (and three) 'movements': to promote different aspects of software availability.
