They probably know their reasons for downvoting, if stated publicly, would be slammed with downvotes. Imagine if HW posted their reasons every time, and I don't mean the bland, "This was plagiarized/spam" bot comments. They would actually have to display compassion and creativity in explaining individually to each person why they downvoted it. Uhnph! Setting up a good customer service department for $3k is a lot of work, and was never part of the plan.
I'd support a $3000 fund for them to start doing nothing to anyone.
