As a researcher with many articles in the ACM library, I have to say this is a masterclass in hypocrisy. Obviously, lawyers can decipher the terms of ACM publishing contracts and Creative Commons licences to determine if this will be acceptable or not. But ACM is not a company, it's a non-profit founded in 1947 to represent scientists.
I would be surprised if a majority of ACM members were to say yes should we ask them (but ACM is not known for such democracy). Along with book authors, we are one of the many people that provide the knowledge and expertise on which large tech firms train their models, and get nothing in return. Actually, life is getting worse for us: extra workload in universities with students' AI use, a completely broken peer review system, etc. Hence the irony of ACM thinking about licensing, and only licensing, at a time where this is the least of our priorities.
