The Jo Freeman article was written in retrospect to her own experiences with the feminist movement in the 1960s - she has another article - "Trashing: The Dark Side of Sisterhood" - that I think illustrates very well that in spite of her belief of the movement, she had been hurt by its methodology (which was by no means exclusive to the feminist movement, as we see here) and not to mention was in no position to be able to "take power." She wrote these things in hope that the movement could course-correct, not out of some calculated Machiavellian strategy.
I think perhaps I could have been more perspicuous in my post, as both replies to my original post seem to focus on specifics when I'm talking about the more general case. In that regard, I'm not talking specifically about flat hierarchies, feminism or these individuals (though certainly it is true in some cases).
