I can't think of a single company (besides maybe a tiny start-up where you know all of leadership) where airing ethical grievances through a private, respectful, official channel would accomplish anything. If you're at the point where you're objecting so strongly to something your company is doing on ethical grounds, you're 99% of the way out the door already.

Better to just quit and if asked, quietly note the reason in your exit interview. Banding together and politely petitioning your company is not going to change anything--your employer is not a democracy. And obviously protesting your employer publicly is not going to help, either.

I didn't quite soil my pants like that other guy, but I at least mildly chuckled at the thought of telling my manager in my next 1:1 that I object ethically to some business my 10,000+ person company is engaged in.

Hey you seem rattled by that. I'm just humorously, and therefore much more kindly pointing out something that could sound cruel if put plainly; that you have a naive and distorted understanding of human relations and offer really, really bad advice. But you seem stuck on appeasing tyranny, so good luck with that. It never worked. I'll be in my mom's basement if you need me :)
