Who decides which philosophies are extreme?
I don't feel like preferring a FOSS solution in a situation where there are plenty of good choices is that extreme. That's why I asked.
If anything, I feel like "Use the best tool for the job and ignore all other factors" is an "extreme" stance. (although Stallman's obviously is as well)
Are you of the "anything goes" thinking? I for one, find that attitude TOO extreme. I don't wish to accept (or even tolerate) "anything" just because someone else finds it OK.
