I forget the exact wording of the quote I want, but it was something along the lines of "It is almost impossible to get someone to notice something if their continued employment depends on them not noticing it."
> if their continued employment depends on them not noticing it
A lot of these reviewers review for these journals for free, maybe because being known as a reviewer for a prestigious journal is beneficial.
But their livelihood certainly doesn't depend on it. A lot of these major journals pocket all the profits from paywalls, and don't pay the scientists who do the hard work reviewing a dime.
If there were a collective revolt, and all these scientists switched en masse to an open publishing system/platform, this scam would end then and there.
