>> If an author did not grant license to his code, then nobody can use it, by default, according to copyright law. this is false. Fair Use is not about the license, it is a set of exemptions from copyright. for example I do not need a license to reproduce and publish a snippet of book for the proposes of review / criticism. The author may not like what I have to say, and did not grant me a license but I certainly can use the snippet under copy right law. The Legal Experts of ML are relaying I believe on the "education" exemption in Fair use for their "training of ML models is fair use". That will be an interesting case for sure
