I'm afraid I have to disagree. One of the replies to your cited e-mail made a more accurate statement, that Linux *distributions* are about limiting the user. That I can agree with; one of the factors in choosing a particular distribution are the choices which have already been made for you. Few individuals want to design their own distribution from the ground up; even Linux From Scratch has a standard template for the base system.
However, were it not for the freedom to make unpopular choices, including the choice to develop an alternative to an existing "good enough" solution, we wouldn't have Linux in the first place. Anyone who works on Linux is already exercising that freedom, which makes it hypocritical to talk about denying the same freedom to others.
