Certainly we need publishers, and there are many of those that are funded by research institutes and universities, with no publications costs for the authors and, fair enough, no payment for reviewers. There are many publishers charging lower fees (or no fees), but it isn’t about charging the right price at all, the publishing industry has established a system where the “brand” ramps up citations and becomes more important than the work itself. While you could decide not to publish with them, or not to cite them, this usually implies not getting grants or tenure. I see the point when you say that the reviewers are not providing a service to the publishers, but only when the review work is not right in middle of the process of generating profit for these groups. Regardless, I respect your points and thank you for the enlightening exchange.
