I think ethics will often fall short in general. I don't mean this to be limited to the comment above by the threadstarter, but when it comes to money, most people will choose money. People will have different threshold levels of what they want to accept.
If OP's story is true, it is commendable. Not everyone will choose principles over money.
I was in the past in the position of working for a corporation I personally consider to be vile, damaging to the world and society. Took me about 3 years to move elsewhere. I was not in the position to just quit, both due to finances and due to visa requirements.
I don't fault the common man for having to put up with things. But I will commend those that have the fortitude to at least turn and walk away.
Using a survey like this is IMO not ideal though.
