Why so? I think this is the way to be promoted/lead things. You don't have to live and die with your project but there are definitely a few opportunities that are opening up if "you care and army that doesn't". I believe calling your colleagues "army that doesn't care" is a bit disrespectful and this is what is wrong with "I care so much" people at big companies.
upd: I did generalize "I care so much" people as well; but I do consider myself one.
