An AT&T staffer giving me a data center tour circa 2006 told me only one of the VPs knew who the client was for one of the areas in the room. What is a staffer going to do to influence that kind of situation?
This isn't an option for a lot of people; the folks doing tech support or working in the shops and barely get along on minimum wage don't have that option. The decision makers and tech leads do.
I'm not talking out of my ass. I have resigned from a very well-paid position because of ethical reasons, and there was far, far less at stake than general privacy matters.
