I'd actually say it's one of the primary motivations, but then I think that's the reason most people do most things. On the second point freedom doesn't exist in a vacuum and exercising ones freedoms almost always involves impinging on the freedoms of others. Therefore there is a constant negotiation going on that involves the balancing of freedoms of different individuals, not to mention the balancing of freedoms with other ethical goods that people value (like equality, happiness etc.) There is very little recognition in the fsf / open source world that adopting a maximalist approach to a specific set of freedoms - those that fit into the free software / open source ideology - necessarily impinges on other freedoms that many people also value - like the freedom to own and profit from one's labour without further enriching google et. al (Yes there are differences between the fsf and open source camps but they're largely of the peoples front of Judea / judean people's front variety.)
