I probably should have gone into more detail on predatory journals, but I do address the issues you brought up later in the paragraph. My biggest concern is that the informal concept of what is called a "predatory journal" could easily be weaponized to serve the ends of established publications. This kind of discourse is important. It's been my experience that corruption intrudes upon every enterprise and you are always met with hostility when you point it out. I've had some wonderful conversations with individuals on the price of their contributions to scholarly journals, and some of them had a "wake up" moment when they realized how much they had been spending. It's important to have these conversations. But yes, I'll also admit that I knew my title and language would be considered provocative. This is the internet, that's how you get comments, clicks, and engagement.
