You said yourself: "if you are fired, you would be beyond fucked with your life, so you pull an all nighter." If you don't think that's abuse, I don't know what else to say.

> We must either move back to our home country or avoid doing all-nighters. We have no free will to make our own decision. We are to be labeled as an abused person forever.

I really don't understand what you're saying here, especially about "free will". My impression is that you seem to be implying with your response that bosses demanding all-nighters is fine, but a mere critical comment from a stranger on Hacker News has equal authority and power, somehow even worse and immoral. But that would be quite overdramatic, so maybe I'm misunderstanding.
