[From my comments in the rebranding survey]
"Movement"
Please stop calling us a "movement". I am an active Wikipedia contributor, but I do not feel part of a movement. Know that I feel excluded when we are referred to as a movement. I would guess that most Wikimedians do not consider themselves part of a movement. I feel that I am part of the Wikimedia _community_.
Note that in the English Wikipedia the title of the relevant article is indeed "Wikipedia community", _not_ "Wikipedia movement" (which is a redirect). In fact, the word "movement" does not appear in the main text of the article at all. "Wikimedia movement" is the title of its article, but it is described as "the global community of contributors to Wikimedia Foundation projects". A community of contributors is not the same thing as a movement. I would say that none of the definitions given in the Definitions section of the Social movement article apply to us.
One significant problem to using "movement" is that some, including the WMF, exploit the connotations of the word towards social justice, or a "greater good", as a rationalization for behaviors that a community might not support (and in many cases our community has indeed opposed WMF's behavior). Another is the implication that there is basically a core set of beliefs and priorities that all those involved support. This is clearly not the case in the Wikimedia community. I also think there is an assumption that in a movement, there are institutions that those in the movement explicitly or implicitly authorize to speak for them. Again, clearly this is not the case in the Wikimedia community overall.
