Honest suggestion: you should submit your own Show HN post for that. I reckon you are being downvoted for "hijacking" another post, not based on the merits of your project.
I never said that had to be downvoted or upvoted. I was just advising him/her to create his own Show HN post to follow this site's rules first, and to maybe get real feedback about the site.
Regarding "copyright abuse", it depends on multiple factors IMHO, but that was not the point of my comment at all.
