I understand reading it as benign and sincere if you're sympathetic to the sentiment. As someone whose job it is to read the comments all day every day, and whose objective is to keep discussions here as intellectually gratifying as possible, it just comes across as unsubstantive at best, and jeering at worst.

The project is open source; if the commenter was sincerely curious about what the software does with a user's code, they could have checked themselves or phrased the question in a way that made it clear they were genuinely interested in finding out.

My reply wasn’t hostile or threatening; just a polite reminder to use HN in a way that’s consistent with its intended spirit.
