I mean that's good for you and I tend to agree. But it's incredibly naive to think that any significant percentage of the working population is using that criteria to determine where and on what they should work. We tend to think of tech people as being incredibly bright but at the end of the day they are human and FB is a very cool place to work. If you don't take a minute to evaluate the ethics of the work you're doing which might not on the surface be all that questionable it's easy to fool yourself into thinking, you're doing nothing wrong. It's a much easier realization that working for Defense Contractors making missile guidance systems is bad than it is to think hey all this data i'm collecting for my social network features could be put to some very bad uses
