A notable feature of stacks of stones is that they're easy to knock over. So if you don't like them, knock them over. It'll make you feel good, to the extent that you don't like them. So it's a way for stackers to help topplers feel good about themselves. Toppling stones is actually strangely satisfying, like stomping a sand castle, starting a domino avalanche or exploding a death star. Cumulatively the number of stacks will reflect the balance between stackers and topplers, so it's democratic. Myself, I don't care, but I have other pet peeves that I do care about for very little reason. Stickers that are hard to remove from products, for one. Now that requires urgent action.
