I've not yet had to actually tell a recruiter no for moral reasons, but that's mostly because I don't apply to companies whose behavior I consider immoral. I was last recruited for a FAANG company about two years ago and at the time I didn't have the issues with that particular one that I have now; they just didn't have what I was looking for. However, I did interview recently with a (software engineering) consulting company, and I made it clear to the recruiter that there were some industries for whom I would not do work. She responded that they do not as a matter of policy work for those industries, so there wasn't anything for me to worry about. I ended up taking a different opportunity for unrelated reasons. I recommend that you be honest and straightforward with the recruiter. It won't hurt you or them any. They ought to reconsider working for an unethical company themselves, if they're in a position to do so.
