This is stupid. There are two completely separate variables here.
Peer reviewers review publications as part of their service to their respective communities. Unpaid.
Peer reviewers are PAID by their respective industry for the fucking job that they perform for that industry. Paid.
Imagine saying that soup kitchen workers were paid one billion dollars last year. In reality, the soup kitchen workers WORK FOR FREE. They have OTHER JOBS in which they earn money.
This is divisive, disingenuous bullshit.
