I’ve mentioned before some of the reasons for academics not to do business with the publisher Elsevier. A bunch of scientists boycott Elsevier journals. I’ve just signed onto the boycott myself, and I urge my colleagues to do so too.
To be honest, this is an easy stand for me to take, since there’s pretty much never a time when refusing to publish in an Elsevier journal imposes a significant cost on me. For people in fields in which Elsevier journals were clearly better / more prestigious than others, the situation’s a bit different, I suppose.
