You are absolutely right.
But on the other hand: Those I described exist too.
I have seen Linux addicted academics in UK, France and Germany.
They are hardcore, they can "speak" - meaning, they will be able and willing to create a lobby for freedom and Linux.
It's not that I don't also see the people you describe.
But are they as "loud", as "verbal"?
I wish they are - don't know too much of that group, but I hope they are.
They only have to get rid of their Stockholm syndrome
