Correct me if I'm wrong, but you're saying the ethically questionable work will not be the most serious from an engineering perspective and thus less interesting for a hard-core security engineer. If that's your position then I think it needs to be fleshed out more than just saying you can amorally and categorically reject contracts from Narus or the US Govt. What is fundamentally uninteresting about their systems? I'm sure a lot of engineers working on PRISM et al found it to be very technically challenging and rewarding work.
