Let's cut through the nonsense here, you're advertising your product in someone else's post, and successfully became the top comment in doing so. Thus diverting any other discussion on the authors work, to only yours. I'm all for good discussions, that's why HN is my only forum I participate in, but doing this, in my opinion, sucks.
Yeah, now all the top top-level comments are plugs. This is ridiculous.
Someone else's Show HN should not be an avenue for marketing your project, plain and simple. Maybe people will start organically talking/comparing to a competitor, but even that is different from the ol "hey everyone, here's my alternative!" which is just sheepish.
Time to leave the theater so other people can enjoy the show.
I think you are in wrong website. This is where people build and share with eachother. I shared links of two open source projects that can help this product, too. Obviously you are not an active contributor to the community, so you take see it differently.
