If there's a large contribution to a library X licensed under Apache v2.0 from user A and user A decides to create a friendly fork of the contributions he/she made in library X to a new library Y licensed under MIT license. Both Apache v2.0 and MIT are commerical permissive license. But would that be legally okay? Are there guidelines or best practices on such scenarios of friendly fork?
