Are there boycotts against publishers other than Elsevier? Academics have called for a boycott against Elsevier, with some success for instance because it has led to resignations (recently in the Lingua journal).

As I understand it, Elsevier is not the only publisher with absurd subscription prices, but it is being targeted because it is the largest one. Are there any similar initiatives against other publishers? (Springer, Wiley, Taylor and Francis, ...) If not, why?
The Elsevier boycott seems to be the largest one of its kind.  I understand the argument to be:


A boycott is easier to maintain against a single publisher than against several publishers at once, since it limits the cost to the participants while, if anything, making the boycott more painful to the publisher.
There's a short list of likely candidates for a single boycott---probably just Springer and Elsevier, and perhaps Wiley, as the largest and most expensive academic publishers.  Elsevier had been particularly active in lobbying on some related issues (SOPA, PIPA, and the Research Works Act), and had recently been involved in several publishing related scandals (the ones involving Chaos, Solitons, and Fractals, and the Australasian Journal of Bone &amp; Joint Medicine).


(I personally found these arguments strong, but plenty of people didn't, and some people have refused to participate in the boycott precisely because they think such a boycott should be more widely targeted.)
