Thanks for an excellent article. I believe it could have been written to address not just BSD acceptability, but also Linux and Open Source generally.
The respectability vs. demagoguery debate hits close to home.
When arguing the case for one technology over another, it is important to see the "battlefield" in simple business terms. I find that open source solutions often win in the end-- especially given their affordable price tag. Managers may be reluctant to adopt new solutions quickly, especially with mission-critical functions. But, they tend to soften up with a few success stories under their belts-- and some dramatic reductions in software costs.
