I am a dual CS/Philosophy major, and this is my take as well (with respect to the general moral attitudes of my CS peers).

I've been agitating for an ethics class in my own department for about a year now, to little effect. Reactions to my proposal have ranged from sheer disinterest ("ethics? who cares?") to snark ("not until the next big scandal") to outright (admittedly plausible) dismissal ("we'd have to remove something else from the syllabus"). It's been disheartening, to say the very least.
