That's true for some of what's posted, but it's the very much the wrong verb for a lot of the commentary from A5cent, Spaulagain, me, and others. Here's how you can tell:
Whining: to utter a low, usually nasal, complaining cry or sound, as from uneasiness, discontent, peevishness, etc.
Critiquing: evaluate (a theory or practice) in a detailed and analytical way.
Now, although my tongue was in my cheek for much of that, the point stands that there are valid arguments to be had about what we've seen (and even pencil-drawn mockups). Of course, there are invalid arguments, too. Let's try to avoid the latter ones.
