Most still get benefits. I concede that many don't get "direct" remuneration. Some journals do pay.
But many do get vouchers, discounts, free access, early access, etc. which amounts to a form of payment and thus compensated in kind. This effectively is "paid" as far as I am concerned.
The logic stands. A reviewer, even those who get zero compensation, can always review publicly published papers just like others.
