The core of my argument is that an engineer building the product is performing their duty. You don't have to sell me on the fact that ads are bad. I hate all ads. I'm a developer myself and I've never faced the dilemma, but I don't feel like blaming others for not wanting to become judges of good and evil. Like in the case of a lawyer, doing your job and doing it well is in and of itself ethical. I really can't draw a line in the sand where adtech is unacceptable but $something_else is, just because I have such an hatred for advertisement.
