I try to avoid such unhelpful comments, but it may be justified here; an account clearly created for purposes of self-promoting post, paired with a comment that reads like a generic cross-platform press release (spam)

From the guidelines[1]:

"Please don't use HN primarily for promotion. It's ok to post your own stuff part of the time, but the primary use of the site should be for curiosity."
