A large group of scholars has signed a petition protesting the creation of a new subscription journal from Nature, Nature Machine Intelligence.

They argue that most journals in the field are open access with no charges for readers or authors. The people signing the petition have said they will not submit to, review or edit for the journal. I’m not sure how large the machine learning community is, but the petition has over 2400 signatures (as of May 2nd).
Nature has stated they respect the opinions of the petitioners, but they feel the new subscription journal can co-exist with others by providing an outlet for interdisciplinary work that has undergone rigorous peer review.
