Wikipedia is estimated to be the sixth most-visited web site in the world, and is the only site in the top that is commonly referred to by the word "wiki".

You are free to complain about or dislike that, and to want people to broaden their horizons if they think of it as the wiki or as the default thing that "wiki" refers to, but you are not free to claim that most people, when they say "wiki" as a shorthand for a site, actually mean some other site, or that some other site which could be called "wiki" is more likely to be meant.
