Before I get to that, I'm going to explain the word 'indication' to you like an idiot, because it's clearly the only way to get it through your skull.
Indication: Not exact. Gives you an idea of. Doesn't necessarily point to the truth of a thing. For example, your complete failure to understand simple concepts gives me an indication that you're not very bright. That might not be accurate, but the signs point that way. Similarly, unless there's a spec where the numbers are wildly different from the others, we can probably surmise that there are no outside factors which are significant enough to suggest that these numbers don't point us in the general area of the reality of things.
That brings me neatly onto Guardian Druids. You're right, they are over-represented (albeit at about 2% of the total population vs about 0.6 for the other tank specs, a staggering difference of less than 2%) and that does suggest that something could be different in their case. Spoilers: it's still not the skin. Instead of just guessing like you did, I did some research, and it turns out that on release, Guardian druids could cheese the encounter, which neatly explains the disparity.
An indication, by its very nature, is to be taken with a pinch of salt. The available evidence, however, would tend to suggest that your assertion that some skins are so ugly that significant numbers of players will not use it, relative to other specs, is either incorrect, or does not apply in enough cases to make a significant enough effect on the data to render it unreliable as a ball-park indicator of numbers.
So, I've explained Guardian Druids; tell us, wise one, which are these specs whose challenge appearances are stopping huge swathes of players from using them, and what is your evidence?
