so? the gist of the mit license is, "use without restriction". without the license the default is that you have no right to the work, so the license is what makes it a gift. you're welcome
no it very much isn't use without restriction - you must credit the the author and otherwise follow the licensee. I can't copy and republish code from the Nvidia driver leaks because those are copyrighted by Nvidia (unless I have permission from them). In the same way you cannot copy and republish code from a MIT project unless I have permission from them (via the MIT licensee).
