I don't think it is an "either/or" here. I suggested market demands as a factor, not as the sole exclusive answer. Though I think some universities are more susceptible to market demands than others (those with big emphasis on career placement programs or cooperative education internship programs, for instance). Also, there's a lot of peer pressure between universities and from some points of view many parts of that can also be considered market demands though not the market you thought I meant (who is writing and selling the textbooks and other teaching materials? how expensive for lab computers and students are compilers/tools/IDEs? how many other professors at the school know the language for later classes? how easy is it to hire professors that can teach or accept assignments in the language?).
