A basic view of it is: a man keeps his promises.
What do you think of people who don't keep their promises to you? Do you congratulate them on their successful use of game theory?
If you saw a wallet with cash in it and an ID card lying on a park bench with no one else around, what do you do? Would you behave differently if it was $5, $100, $10000? Are you a man or an animal?
A few months back, there was an article in the newspaper about someone who found a very large sum of cash, in the 5 figures. He figured out who owned the money, and gave it to the owner. Then he became infuriated because the owner didn't give him a "reward" for being honest.
That's not how honor works.
“It’s not honorable.” could translate to “Het is niet eerlijk.”
E.g. het is niet eerlijk om je werkgever te vertellen dat je 8 uur werkt maar maar 4 uur te werken.
Of course, I think the original relation with the word ‘eer’ has been lost and it’s mostly it’s own thing now.
I thought that honor could also be about that if one gets insulted that the insulted person would start a fight because his honor was insulted (apparently this happens in the south of the US a lot, according to psychological experiments [1]). I remember when this happened to me. Someone in SF said "fuck you" at point blank range with no reason. I simply ignored him, I didn't get all up in his face. But apparently, people from the south do that to defend their honor.

I mean, in current usage, probably yes. In English the words do not seem related, but in Dutch it seems that lying is/was considered dishonorable. Dutch people certainly seem straightforward compared to other people I’ve met.
I guess different nationalities consider different things as affecting their honor.
Stating upfront that if I feel underpaid is a very very bad thing for me and the company, because it undermines my motivation (yep, that's how I say it, I also give numbers and explanations behind those numbers) is an honest upfront thing to say if you ask me.
When people push through, then they push through because they don't seem to care about that. All they focus on is that they can get developers for (too) cheap. I just warned them. I'm not warning them again. Note: obviously this only happens if I need the job/money and I'm in a tough spot. Otherwise, I'd walk away.
FWIW: I don't know much about honor, ("eer" in Dutch, who uses that word even? I almost never hear people talk about "eer"). To me honor seems like pride and I've seen people defend very stupid things because of pride. I'd rather defend something because it helps humanity with the contingency that I can at least be moderately happy myself.
Because of this what I do care about is truth. For it is truth that will lift us (slowly) out of whatever miserable stuff we endure, and I can get behind that. Unfortunately, other people don't seem to care about it as much as I do and I have been burned in the past.
Edit:
FWIW I welcome this discussion as I feel people tend to think differently about these things based on all kinds of factors. I think these different views are interesting since it allows me to ask questions that are relevant to my personal life but I'd otherwise not think about.
