Please articulate your concerns with this. Is it because it's copyrighted? I think most open source software is under copyright; but the license (MIT in this case) grants end-users certain rights that can be revoked if that license is broken.
Hey. Sorry, it appears that I am totally wrong. I just assumed that those statements were totally conflicting, but ten seconds on Google tells me that’s not so.
Yeah usually open source software grants some permissions but retains copyright ownership. This somewhat disallows abuse of Open Source projects, and is probably part of what makes something like the GPL enforceable in court. IANAL
No, you're reserving all rights that a copyright indicates and then granting specific exceptions (i.e. "I won't enforce my copyright against you if you follow these rules") without giving up those rights
