The point I see is that Stallman is termed by Tim to be totally inflexable whereas Alchin would be more open minded. Not having personally met either one from what I have read over the years that is probably correct. Now the proposition that all software should be free is as correct as all software should be good. An admirable concept but hard to advance in the real world. Microsoft has made a lot of money by being "good enough" and cheap beating out a lot better more expensive software.
Actually I dont have a dog in this fight since my income is usually trying to get disparate software running on disparate hardware so people who actually do productive work can get to it.
thanx,
