Computers may have been invented out of intellectual curiosity, but they were produced for war. Now what?
Check out http://en.wikipedia.org/wiki/Fritz_Haber -- just the glasses should be enough to tell you this man might be very evil, and he is indeed "the father of chemical warfare". But wait, he's also responsible for the discovery that allows huge numbers of people to live. Now what?
Let's simply assume Brendan Eich is a very evil man, that prop 8 is just the tip of the iceberg. Well, but, Mozilla. Now what?
How about this, if you propose to throw the baby out with the bath water, find us a new baby first? Let's use computation machines invented for love, let's use fertilizer invented by someone who had at least contact lenses, let's use browsers and languages made by catholic priests who secretly marry gay couples and get hunted all over the world by the pope for that.
I'd be down with that... but first they need to exist. Until then, to let billions of people starve, or to give even more of the web up to Google and Apple, is not actually morally superior to the alternative of realizing that life is messy, humans doubly so, and we don't just owe a lot of what we take for granted to saints, but to the whole spectrum.

That in itself is a rather vicious and dehumanizing view. It's awfully convenient to have people who are pure evil while you yourself are pure good -- it's also nonsense.
