I think it's awfully arrogant to assume that we require an explanation for every knob. It may very well be a proprietary function. Which means no, just use it and be happy, before he decides he has to take it away because of to many questions. To my ears, it adds, and takes away a certain crunchiness, so aptly named. I like it, I don't care what it actually does, it seems to work to make my patches do what I want them to do. I am happy with that.
I think it's awfully arrogant to assume that your opinion on what matters and what doesn't should be treated as law, and use that to judge others as "arrogant."
You and some others seem to be missing the actual point here though. The issue being taken with the response is not that it's not giving some kind of detailed, "needs an electrical engineering degree to understand" type of response (which, until recently, was the norm for how Cliff would generally answer questions like this, because, you know, he's basing his business on the idea that the unit is replicating real world hardware), the issue that people seem to be taking is that it's a non-answer.
I'm sure the people asking would be happy with:
"It replicates X"
"It's not replicating anything"
or
"I refuse to divulge what it's doing." (which he has not said at all)
Instead, people that are using the unit in various ways (some of which are dependent upon replicating real amp rigs accurately, which is something that a number of people on this forum completely negate every time they write off someone's questions with "just use your ears") are getting the answer "crunch does crunch." Which is as non-answer as you can get.

"And what does that little red button do?"
"Oh, that's the Schwoop button."
"What does it do?"
"It adds schwoop to your drive."
"What does that mean?"
"It makes your rid more schwoopy. Didn't you feel the added schwoopiness when I pressed it while we were on our test drive?"
"I mean... I felt something change while I was driving, but it'd be nice to know exactly what it's doing."
"It increases the schwoopy factor of the car's performance"
