What is ""free use"""?

"Free use" refers to the ability to use a copyrighted work without obtaining permission from the copyright holder. Such use may be permitted under certain circumstances, such as under fair use or the public domain. Fair use allows limited use of copyrighted material for purposes such as criticism, commentary, news reporting, teaching, scholarship, or research, without obtaining permission from the copyright holder. Public domain refers to works that are not protected by copyright and are available to the public for free use. It is important to note that the rules around free use can be complex and vary from jurisdiction to jurisdiction, so it is always best to consult with a legal expert before using copyrighted material without permission.
