These guys are _very_ good at selling, in other words, making something seem good and pure and beautiful. I ended up in an almost identical company doing identical tech. At first we were building an anti-spam platform for which the user would only see two ads a day from us, and none from anyone else. Seemed like a good trade off. Except we never got to the anti-spam bit -- just the ad bit. I was gone within 3 months of arriving.

It might have just been that particular company at that time, but I've never worked with so many morally questionable people at one company. Never again.
