A very weird move. They are now taking a stance on what science is supposed to be.

As someone commented, due to the increasing volume, we would actually need and benefit from more reviews -- with a fixed cycle preferably, and I do not mean LLM slop but SLRs. And in contrary to someone's post, it is actually nice to read things from the industry, and I would actually want that more.

And not only are they taking a stance on science but they have also this allegation:

"Please note: the review conducted at conference workshops generally does not meet the same standard of rigor of traditional peer review and is not enough to have your review article or position paper accepted to arXiv."

In fact -- and supposedly related to the peer review crisis, the situation is exactly the opposite. That is, reviews are usually today of much higher quality at specialized workshops organized by experts in a particular, often niche area.

Maybe arXiv people should visit PubPeer once in a while to see what kind of fraud is going on with conferences (i.e., not workshops and usually not review papers) and their proceedings published by all notable CS publishers? The same goes for journals.
