I think it’s just because the answer doesn’t really contribute much. OP is asking about something specific (and kinda interesting, too!) and your response was “I don’t know, I don’t use that software”. It doesn’t really add to the conversation or help to answer the question.

Imagine if every question that got asked was responded to by the entire community, even if they had no answer, and every thread was just filled with “I dunno”.

No hate on you specifically, just thinking out loud a bit.
