Maybe because I'm not especially interested in passing moral judgment on others, for working at a company that isn't a "moral high ground" company, but isn't exactly NSO or Palantir (I used to work for a defense contractor). I feel profoundly lucky to have found a company that made me feel good about what I did. It was worth the low salary (and other annoyances). I understand that I'm fortunate, and I'm grateful (not snotty).
I find that people take the mere existence of others that have different morals to be a personal attack.
I know that it happens, but I'm not really sure why. It's not like I'm thinking about comparing to others, when I say that I worked for a company that inspired me. I was simply sharing what I did, and why.
I read comments about people that are excited about what they do, and even how much they make, all the time (I spend a lot of time on HN), and never feel as if they are somehow attacking me. They are enthusiastic, and maybe even proud of what they do, and want to show off. I often enjoy that.
