I am skeptical it is a problem isolated to Elsevier. Given the LLM craze now prioritizes open access, https://andrewpwheeler.com/2025/08/28/deep-research-and-open..., it would not surprise me people start gaming MDPI in the same way for example.
I'm certain that the comment you responded to never claimed that it was "isolated to Elsevier" in the first place, nor is it very compelling to speculate about how in the future something even worse might emerge.
Right now Elsevier is by far the biggest offender and also happens to the be the topic of the conversation and the article.
Exactly. Elsevier is a dominant company. Of course it's going to have a huge share of anything that goes into journals. They probably also have a huge share of the Nobel prize winning papers too.
That being said, I'm happy to encourage open access.
MDPI is gamed by design, I think that while Elsevier is awful, MDPI is even worse with 100s of special issues where you are guaranteed to land publication in journals with quite nice IF (which is inflated by publishing large proportion of reviews and less original research).
