OK, I definitively get it proprietary software, however how does this apply in the following context: * the submitted work is quite old (first commit was in 2011, although there has been some activity in 2019 and 2020); * the submitted work was not already published on HN, and given that it is from around 2011 with a few releases since then, and that it wasn't yet submitted on HN, I don't think I took any "credit" from the authors which might have subsequently submitted it themselves; (because they would have submitted it in the interim if they wanted to;) (moreover I clearly disclaimed it in the comment immediately after publishing it;) * the submitted work is quite useful and not well popularized; (I sought for such a tool a few months ago, but failed to find it;) * the submitted work is open source, thus by definition anyone can fork it, modify a single line of code, and now he is one of the authors; Basically I'm asking: how should one submit software that wasn't developed by themselves, but which ultimately is useful and can be tried by anyone. Should I submit it as a link? I thought that plain links are mainly for "writings", and that "Show HN" is mainly for software.
