I think people should draw parallels between sci.publishing and social media. They also ask unpaid individuals to publish their writings, then ask other unpaid individuals to review and rank them, then use their algorithms to editorialize and pick the ones they like and then make exorbitant profits. Some of then like youtube will subsidize that with increasingly dwindling payouts , but overall it is a scam based on monetizing content created for free by clueless individuals. Participating in unpaid social media should be considered an equally extortionate thing to do.
