Your keep calling people "competitors." I don't think you're using the word right. Perhaps "detractors" is what you mean, but "reviewers" is more neutral. Xe and mawfig don't appear to be offering their own languages to compete with V. At one point, Andy Kelly (a "competitor") criticized the author's behavior, but he's also gone silent on the topic of V because of the vitriol he encountered.
One reason that people highlight older criticism is because it's useful to examine past behavior, past promises, and contrast them to current behavior and current promises. If V is going to improve its reputation, it's going to do it by (a) making good on the promises it can, (b) coming clean on the promises it can't, and (c) offer a clear win for some distinguishing featureset. Badgering people to shut up about the past isn't on that list.
