Who said anything about "freely available for use"? The whole discussion here has been about proprietary licensed works. Karunamon said that proprietary licenses did not exist, because works are automatically copyrighted and I disagreed.
A project on github without a license is not proprietary licensed, but they are copyrighted. If such work ends up in the hand of someone which is not the author, then one would have to ask under what permission (license) that happened.

The content of a project on Github that is publicly viewable arguably also is minimally licensed as required by the Github terms of service, to wit, the Github project owner "agrees to allow others to view and fork" the project repository (see Github Terms of Service [0], F.3).
