Well the fact that downvotes in their current state are a loss of curation rewards is the reason for the 2.5 free downvotes. Yes some will (and do) see a loss in author rewards due to them, and will continue. I think I covered those as well though, I just think they are different things. One being the reason the "free" downvotes are needed and the other being a flaw in our current culture surrounding downvotes. I hope as they become more normalized the abuse will stop too.. and I mean it when I say that includes the countering of unjust downvotes.
Can't you watch the downvotes while on the beach? ...
I'll be watching the ships roll in :)
