I think you make some excellent points, but I'd like to share some perspective from the outside (and from someone who strongly supports Mozilla and its mission):
> Let's put this in context, though: This isn't a press release, nor is https://blog.mozilla.org/ux/ a press channel.
That distinction may be well known internally, but nobody else knows or cares to learn about it; we're going to base our judgement on impressions: The page says "Mozilla UX" in big letters at top and it's on the mozilla.org domain; to me and I suspect to almost everyone else outside Mozilla, it's official Mozilla communication.
